’m confused though, if a person of either sex is only attracted to people with female bodies, in the case of casual sex what does it matter how they identify?
If I was single and out looking for a sexual encounter, I wouldn’t care whether it was with a heterosexual, bisexual or lesbian woman. Sex is sex and a body is a body, and as longus consent was mutual, what label they stick on that body wouldn’t matter to me in that moment. Obviously for a relationship it’s different, and I wouldn’t want to enter a relationship with a heterosexual woman
I can only speak for myself as a lesbian, but for me while I agree with you to an extent and probably wouldn’t rule out any natal woman as a sexual partner just because of how she labelled herself, there is a difference between sleeping with lesbians or bi women who have had a lot of experience with women, and sleeping with straight women. The latter tend to be simply less good at it, more inhibited about women’s bodies, and it’s hard to shake the feeling that you’re being used as an experiment. Total generalisation, of course, and won’t apply in all situations, but in general there’s nothing sexier for me than an out and proud lesbian who really, really loves women’s bodies - that’s far nicer to be intimate with than a straight woman who’s trying out something new.
