hmmm.. i know it's not nice to say this but i gotta say it. NEVER mess with a virgin! you never know how much it means to a gal & how important it is. *F her & then find an excuse to leave her? oh.. that's like so basket thing to do yea.
since u're bk with her now, i guess she's feeling better. next time when u wanna leave her again, think twice. frankly speaking, u guys are still very young. there's alot to do other than sex. find some other things to cheer your gal up
