Yeah, this keeps confusing me a lot. I grew up in a fairly conservative/moderate space, and as a young, not out to myself lesbian it was really easy to just be a "virtuous" young woman who didn't mess around with dating. I understand that at some point in your 20s, your family will probably start talking about you settling down and whatever, but you can always tell them that you don't want to and never will - end of story in most first world countries. I really don't understand this extreme focus on telling a bunch of strangers how you feel about having sex in great detail (that none of them will care about, at all). I believe there are people out there who don't feel attraction toward other people (for a variety of reasons, some of them not so good). I still think the reasonable thing to do is just... continuing to not have sex you don't want.
