I think you just are what you are. Open yourself up to sex , possibilty and experiences
We both have a lot of sex and variations of sex ( being watched, foreplay, dogging, stripping,etc) and have pushed our boundries to the extreme.
I am aroused by two guys together so have NO problem at all watching hubby do this. He is straight, he has never ever been with another guy and has absolutley no desire to be. He has been around it, had oppurtunity, he is just not interested.
I classify myself as 100% straight, and I have pushed it to the limit, I have done everything with a woman that you can physically do, and in my mind they were always a hot guy (*in my blog, in my signature below, under "girl sex" it explains it in more detail)
If you allow the pendulum of sexuailty to be fluid and constant, you must also allow the fact thatsome of us are just straight, and have no opposite sex desires.
