In that case, I rarely get "strange" girls that just start talking to me. I usually have to initiate a conversation, but then I never know if a girl likes me or she is just being polite to continue talking to me. No one ever asks if I'm a good fuck or for my number. I seem to get girls smiling at me pretty often. If I count that as being hit on, then that's about once a week. If a girl does start talking to me, I usually won't flirt back quickly enough and she will think I'm not interested and give up. I need to get better at flirting back so I don't give the impression I'm not interested.
