Well, first, you can't be irresistable to all girls all of the time. Pick a type of girl you want to be irresistable to 🙂
Working out is not necessarily going to do it, having a lot of money is not necessarily going to do it, a huge, uh, yeah, is not necessarily going to do it, and unfortunately, intelligence is not necessarily going to do it (look at some of the guys that girls flock to 😉 ).
I found my bf to be irresistable the first night I met him IRL, and he wasn't rich, didn't have a cut body, etc.
But yeah, every girl is different. Just deal with it. 🙂
oh yeah, and I want PICS!! I wasn't awake when you posted them before 🙁
