Ive had 2 situations like that, 1 was a girl Id known since 5th grade and she always had a crush on me, we messsed around for 2 weeks, and then went of to mess around with abou 8 other guys in about 2 monthes. The other of mine is an ex, but I guess its more than friends with benefits. We arent offically boyfriend and girlfriend, but I still care for her, we just moved our seperate ways after highschool. I still see her pretty regularly though.
