I saw in some definitions of abuse that "threatening to leave a relationship to get sex" was considered abusive / rape.

So my question is, if you are in a committed monogamous relationship that wasn't asexual, is it legitimate to give up on sex, while having no intention to leave the relationship ?

If the partner then cheat, it is viewed as bad, and breaking the relationship. If the partner say "we don't have sex anymore, and that won't do for me, so unless it changes, I'm going to leave", that can be construed as pressuring into getting non-consensual sex.

So the only options are to either leave without warning, or stay and give up on ever having sex.

Basically, two questions :

  1. Should there be any duty to have sex in a relationship, regardless of whether "threatening to leave a relationship to get sex" should be considered abusive ? Edit for clarification : duty as in "to be a good partner, you should not deprive your partner of sex"
  2. Doesn't considering "threatening to leave a relationship to get sex" to be abusive prevent people from discussing their sexual needs and negotiating on how to meet them ?
