I don't go out much, and I've never been to a bar or anything like that en femme, so I've never really had a man hit on me. I have no desires whatsoever to be with a man, either, so I think that were a man to hit on me, it would make me feel very uncomfortable.
I have noticed men looking (or leering) at me while out, but then, it's normal for men to take elongated looks at women wearing pretty dresses. And I did find that rather amusing, and a little flattering. But still, I'm glad that none of them have ever approached me and asked me out to lunch or anything. I really don't want that kind of attention.
