Hmmmm....just trying to put the shoe on the other foot. If I dated a guy who DIDN'T want to have sex for the first three months - I think I'd lose interest before the three months was up, because I would assume this is someone who doesn't have that strong a drive (and that can definitely be a problem with guys my age, a problem I am hoping to avoid).
Don't get me wrong, I'm not sex-crazed or anything - but I still have a healthy normal drive like I did when I was younger and that would be an important aspect of any relationship to me.
