I recently started seeing a girl at work. I'm 21 she's 19. I am a virgin. I have never really acted out any sort of sexual expressions or participated in relationships during my teen years because I had no idea which sex i preferred. I asked her out on a date and we found that our attraction is mutual. She has been adament on not making us exclusive. I've recently been out with a group of friends and made out with a girl that i had long had a crush on. My--for lack of a better term--fuck buddy--decided to curse the day i was born because i cheated on her. Is it cheating if she never established us as a 'couple' until after I hurt her?
