Completely Lost

I'm twenty-six and it seems that I have a split personality with regard to sexuality. When I see handsome guys (especially in underwear), I get excited. More or less, I feel the same for pretty girls. However, I have never had a bisexual act or a heterosexual one. I just had oral sex once with a guy older than me. Once I had finished him though, I started to hate myself for that. I am unsuccessfully striving to get these gay fantasies off my mind. I don't want to admit this myself either. I feel completely lost!
