I'm bisexual, but only in a theoretical sort of way. I've never spent much time around guys, to the point they feel too unfamiliar to be comfortable around, and so I only really date other women.Another element of it is I just don't like the idea of being penetrated. I always top my girlfriends, and I get the impression there aren't a lot of guys who would be fine never putting their dick in me in a relationship.Are there alternative ways to get guys off that might work?
