It makes me uncomfortable and awkward. Probably because I can't relate or contribute with anything to such a conversation.
I know several of my friends have never done anything sexual but they are definitely open about their curiosity about it and that's how we get into discussions about it sweatdrop
If it's personal, then I'd like to keep it between my girlfriend and myself, unless pushed to talk about it; and in those cases, it's only to people I trust. Sex in general, I don't care who's there to hear it XD
I don't mind talking about sexual stuff.
Well, I wouldn't exactly bore a random stranger with details of my very interesting sex life, but I don't have a problem with talking about it with people I know or friends.
Before you start talking you have to take in consideration who might this person be, what are their beliefs, how might I still talk them about it without offending them (of course depending in what way), how could I make them consider something, how could I offend them so they don't notice? Things like that, hey if you want to talk about sex go ahead, just don't start cybering.
