I have always felt I have been straight. I had never had a doubt in my mind that I was gay. I have relationships with girls and felt attracted to them to the point of wanting to kiss etc. It wasn't until recently that I would see a picture of a shirtless guy and get turned on. I don't know if it's just because I am imagining myself as them with that body and attraction of other girls, or if I feel sexual towards them. I have never had a crush on a guy and have never imagined myself having a future with a guy, but yet I still get aroused. I don't know why!
