Still figuring it out

well in 5th grade I accidentally saw porn then it became a habit when I rediscovered it when I got an iPod in 6th grade. It was lesbian porn and I found i liked it better than straight porn. when I was 7 my friend forced me to kiss her but I didn't like it at all cuz I was uncomfortable. I'm 18 now and I still feel confused. I don't know if I'm truly bisexual because I don't see my self dating or getting in a relationship with a women but I wouldn't mind having a sexual encounter with one. Girls are so beautiful and I admire the female form. And it's more acceptable now than ever to admit you're bi. I don't want to "come out" bc I don't know if I really am. Has anyone experienced this dilemma?
