Can someone explain to me what i am ?

I dont know if im gay or if im bisexual . I used to watch straight porn exclusively till i guess about a year ago . Ive even had 2 girlfriends up until now and i enjoyed being with them a hell lot . I love women and their feminine nature . What confuses me is i started reading transexual sex stories and i enjoyed it . The idea of a shemale turns me on a lot . I even watched crossdressing porn and seemed to like that as well. And just recently i started watching gay porn . I have started imagining myself being taken by a man just like how i have done to my ex gfs . I feel confused . i wanna know how it feels like to have sex with a guy and the sense of losing control but at the same time i love girls to . So i dont know what exactly i am . . I dont want any emotional relationship with a man since i enjoy being with women and since being with a woman is what i feel i have a natural urge for .Is it fine to not want any emotional relationship with a man but want the sex and lust part of it?
