Think I am bi.

So yeah, I've never had any type of relationships with another guy, only women. I find women extremely attractive and I see my self spending the rest of my life with women. Here's the thing, I frequently masturbate to gay porn, probably about 65% homo and 35% hetero. I have always loved the way the penis looks and sometimes fantasize about sucking one and having sex with another guy on top of many other things. But, I don't find the male face attractive in anyway. I've never pictured myself kissing another guy and being in a relationship with another guy. But whenever I am done masterbating to gay porn I feel dirty and I a little disgusted in myself (please seriously, no offense). I guess what I'm trying get at, is that I'm super confused, I really want to experiment, but I'm not sure how that I'm going to like how I feel after. Has anyone else been in this situation before?
