Frosty, i hear you on that one.
Alot of girls at my school all think i'm a freak because i want to get big, they say its nasty. As soon as i find that special one that thinks its cool and we click, well i'll be happy !!
As for you being 5'6 chelsea and 125, i don't consider you that big that guys should not ask you out. There are a few girls that are in my gym back home that are probably right around or even over that size and they look Great!
Don't get bummed, keep doing what you love and something good will happen in time.
