When I'm interested in a guy who's flirting with me, I'll usually go as far as asking him what his size is. It wouldn't bother me if he thinks I'm shallow. Especially when it comes to something purely casual, I think it's important for me to see what I'm getting. Some guys I've asked have gone as far as telling me "you'll see it when I'm there" so I never told them to come over. Although one guy who told me that was well hung. Do you guys think it's fair for a girl who might be interested in having casual sex to ask you about your size or would you rather risk getting rejected face to face?
