Asexuals are very vulnerable to a certain kind of rape culture — the type where in a romantic relationship you owe sex to your partner, because refusing to have sex is bad and wrong and abusive. And in asexual communities, there’s a lot of talk about compromise — essentially, having sex with your partner even though you yourself don’t have an intrinsic desire for it. As you can imagine, this can go to very bad places. This is another discussion a lot of sex-positive spaces don’t manage very well, because there’s often very little empathy for the asexual partner (or, in related discussions, the partner with less sexual desire) in that situation. In fact, they are frequently demonised when this comes up.
