am I bi...?

Alright, so basically, I'm confused about being bi. I'm attracted to men both romantically and sexually, which is for sure. But I'm really confused about being attracted towards women. I generally have sexual fantasies about men, but sometimes I get really aroused from fantasizing about women. This might make me seem bisexual BUT those fantasies about women usually involve men as well, which makes me doubt it. Purely lesbian sex doesn't seem to turn me on as much. Also, I'm highly doubtful about the romantic attraction towards women. When I was very young, I think I may have experienced romantic attraction towards women, but I'm not sure because it was so long ago that I don't remember much. I don't think I ever had a real crush on a girl ever since the age of 14 or so. Sometimes I will come across a girl with looks and character that draw me in. I admire them like how I would admire my male crushes, however, it doesn't quite feel the same and not as exciting. Despite this, I strongly believe that it is possible for me to fall in love with one the same way I would fall in love with a guy. Am I bisexual? Am I a temporary heteromantic who just hasn't met the right girl yet? Or am I just plain heteroromantic?
And this is a bit weird... what I like in a girl also tends to be different than what I like in a guy. For guys, it seems like I don't have a specific ''type'' and I'm attracted to a wide diversity of them, but for girls I notice that there is a certain ''type'' in the way they behave and act. I don't know if anyone else is like this or if it means anything.

 

maybe, but I think I do have at least some sexual attraction for women or otherwise I wouldn't get aroused from fantasizing about them... so it's confusing...
