so i was talking to a friend of mine who i've been attracted to, and we started to start a relationship when we first met, but decided to be friends. this girl recently has been screwed over by all the guys she's been with and i've been the only guy whos shes been able to trust and recently shes been wanting to lose her virginity, and jokingly she was like "so.. wanna have sex haha" and it was like an awkward moment, and things lead to one another and we ended up on the phone until 4 in the morning talking about sex, and she wants us to have sex. i'm leaving for the military in august and this is supposed to be taken to the grave. i dont know if i should do this or not. i dont want to lose our friendship and all, so i dont know if this will complicate things. any advice as to what to do?
thanks
