Do Asexuals And Aromantics Have Heterosexual Privilege?
Having role models of your gender and sexual orientation
This definitely doesn't apply to any aromantic and/or asexual people. It's easier to find gay or bisexual role models than asexual or aromantic ones. In mainstream media, asexuality is represented by problematic fiction suggesting we can be cured or are lying, and the occasional interview with asexuals. Aromantics have even less representation - especially allosexual aromantics.
Learning about romance & relationships from fiction, movies, and television
Again, not true for aromantic or asexual people. Although not all romances show the characters having sex, the vast majority imply that they eventually will want to do so. And models of how to discuss asexuality and negotiate ace/allo mixed relationships are not found in mainstream fiction at all.
And as for aromantics, while there are certainly characters who don't seek out romance, or who are in a relationship that could be interpreted as a QPR, I can't think of any work of fiction I've seen that explicitly describes a character as wanting deep personal connection without romance. And portrayals of characters who want sex without romance are frequently negative and colored by slut-shaming - especially if the character is female.
Living with your partner and doing so openly to all
This is probably not a big issue for hetero aces, assuming that they can actually find a suitable partner. But for aromantics, QPRs tend to confuse people, often being mistaken for romance (which is especially problematic for a romance-repulsed aromantic) or else treated as 'just' friendship.
QPRs are also more likely to involve individuals who don't have a compatible sexual orientation (so a heterosexual aromantic could easily have a same-sex QPR). And siblings can be QPRs. Lastly, many people seek out multiple QPRs. If a QPR is mistaken for romance, they could be targeted with homophobia, anti-incest sentiments or anti-polyamorous sentiments.
On the legal side, unless a QPR choose to get married, they lack the legal rights to care for each other in sickness, help their QPP immigrate, or share custody of a child.
And speaking of immigration, both romantic aces and aromantics could easily run afoul of the procedures for detecting immigration fraud marriages. A marriage that doesn't involve sex or where the partners don't have all the trappings of romance with each other (eg don't live together, don't sleep together, have sex with other people, or just generally don't have the right body language around each other) could be mistaken for a marriage purely for immigration purposes.
Talking about your relationship and the projects, vacations, and family planning steps you and your partner are working on.
As an asexual, aromantic prospective single parent, I've found that my discussions of my plans for motherhood often get detailed with questions about whether I'm married, how I plan to get pregnant, and so forth. I also feel afraid to explain my situation fully with people who may be opposed to single parenthood or ART. An aromantic person who is coparenting may have difficulty explaining the nature of their relationship with the other parent(s), or why their relationship doesn't have the trappings of romance. For example if their coparent lives in another residence, or has another partner, they can either let people assume a divorce or breakup is involved or else have a lot of complicated explanation.
A heteroromantic asexual in a relationship would have a more superficially typical situation than me, but if their relationship is sexless or has very infrequent sex, this complicates family planning. They may need to do at-home artificial insemination, or have sex more often than they'd like during the female partner's fertile period. The asexual partner could suffer feelings of burnout or frustration with how frequently they are having sex. All of this issues would be very difficult to discuss without having to get into explanations about asexuality.
Expressing pain when a relationship ends, and having others notice and attend to your pain
This is a tremendous issue for aromantic people. The end of a QPR can cause grief on par with losing a romantic relationship, and yet QPRs are frequently mistaken for friendships - even by the QPPs!
The situation of one person (usually aromantic) viewing a relationship as a QPR while the other one (usually alloromantic) sees it as a typical friendship is very common, and can easily lead to hurt feelings for the one who feels more strongly about the relationship.
Many aromantics grieve when a 'friend' (who they have a one-sided QPR with) announces that they're romantically involved or getting married, because it's generally expected that a person in a romantic relationship will devote less to their friendships. Expressing this grief can lead to perceptions that they're romantically attracted to that person.
Not having to lie about attending LGBTQIA social activities, or having friends in that community
So far I haven't heard of people getting verbally or physically attacked for their connection to the aromantic/asexual community, except by aro/acephobic LGBT people. However, more subtle discrimination probably occurs. I know of a person who had her work with asexual visibility on her resume while applying for jobs, and applied for many jobs without any offers. When she deleted mention of her advocacy work, she was hired almost immediately.
Kissing/hugging/being affectionate in public without threat or punishment
This is definitely an issue for people with QPRs that would be stigmatized or unacceptable romances. My brother and I are very close, and I consider us to be in a QPR, and someone at our church put in an anonymous call to the police claiming my brother was sexually abusing me. It was cleared up fairly easily, but it really frightened us. My best guess is that she took our hugging, cuddling and general comfort with touching each other as a sign that we were romantically and sexually involved. (The fact that she assumed my younger brother was a sexual perpetrator, as opposed to me being a perpetrator or us having a mutual relationship, is clearly sexism at work.)
Dating the person of the gender you desire in your teen years
Dating is a big challenge for both asexuals and aromantics, even if they're attracted to the opposite sex. For romantic asexuals, dating frequently involves being pressured to have sex they don't want, or feeling inadequate because their partner detects and is bothered by their lack of enthusiasm.
Many aromantics are romance-repulsed, and being in a romantic relationship makes them feel trapped or suffocated. A break-up feels relieving. Before discovering aromanticism, they often have a string of short-lived relationships, all ending because they weren't romantic enough or rejected romantic overtures from their partner.
In seeking friendships, many aromantic people described getting 'romance-zoned' when a friend gets romantically interested in them and can no longer see them as just a friend. This often leads to the end of the friendship.
Dressing without worrying what it might represent to someone else
I don't know if this is more of an ace or aro issue, but as a sex-repulsed aroace, I consciously try to pick clothing that doesn't show off my body, to reduce the likelihood that someone will be attracted to me.
Increased possibilities for getting a job or being promoted
As described above, I know of a person who feels that she was hired in part because she'd removed the mention of her asexual advocacy work. I also know of a sex-repulsed ace who was fired for being unsociable to her coworkers because their constant discussion of sex made her uncomfortable. (Particularly her one coworker who liked to brag about her boyfriend's penis size.)
Receiving validation from your religious community, and being able to hold positions in your religious leadership ranks
As I described in my post on asexuality and religious prejudice, someone who doesn't have a 'proper' sexual marriage can experience negative judgment from many Protestant conservative churches.
Aromantic allosexuals have it even worse, because they tend to prefer friends with benefits or other non-romantic sexual relationships, which are very much frowned upon by most conservative churches, especially for female aro-allos.
Adopting or foster parenting children
Aces and especially aros are more likely to be single parents if they choose to be parents at all. Single prospective parents are at a disadvantage for fostering and adoption, especially prospective single fathers. In international adoption, many countries have explicit rules against single parent adoption or single father adoption. In US and Canada there are no explicit rules against single parent adoption or fostering, but private adoption is subject to the prejudices of the birthmothers, and the foster care system appears to place greater scrutiny on single foster parents - again, especially for single foster fathers.
Being employed as a K-12 teacher without fear of being fired for “corrupting children”
I have not heard of aces or aros having issues with this. Please let me know if you have.
Raising children without threats of state intervention
Single fathers, especially of girls, are at a higher risk of being accused or suspected of sexual abuse. When you look at lists of signs of a pedophile, lack of interest or difficulty with dating adults is often listed as a sign. Ace or aro men are therefore more likely to be seen as potential pedophiles than het-het men.
Receiving equal benefits for you and your partner
QPRs are not legally recognized, so aromantic people either have to get married to a non-romantic partner (if they can) or else miss out on benefits.
Legal marriage, which includes:
Public recognition and support of your relationship
Joint child custody
Sharing insurance policies at reduced rates Access to a hospitalized loved one
Social expectations of longevity and stability for your relationship
A QPR has none of those rights, unless it can be disguised as a marriage.
