Never have. Not going to lie though -- I've considered it recently. I'm not really one for "going out"... like I have a small group of friends I see occasionally (girls) but never really do anything more than just going to dinner or the movies or stuff like that. I am not even sure how I'm supposed to MEET guys with the life I have, LOL. Sooo yeah I was totally considering it but didn't want to be one of those weird people but then I hear a lot of people who have success with it. So I dunno.
