SEXUALLY CONFUSED!?!

Okay so before I start I want to say that this post is for advice. I don't mean to come off as ignorant or disrespect AT ALL. I'm 16 and I've always been attracted to people. I would consider myself to be straight. I lost my virginity this year and I enjoy sex with the opposite sex. I'm for sure attracted to males and male dominance. That's not what I'm questioning. Lately I've been finding myself curious, I get turned on my lesbian porn and it makes me so excited. I also have kissed a girl just in a "bestfriend" kind of way and really liked it. I've been attracted to females but I'm unsure if that is just a girl thing or a gay thing. I guess I'm not sure if I want a relationship with a girl.. But maybe just to have fun with her...? Does that make me a bad person? Is it just experimenting. Is it considered "disrespectful" to think this way? Should I make a move?
