Bisexuality is harder than being gay?

I think I actually might be bisexual or gay in some sort of way. I am starting to become less homophobic and starting to appreciate men sexually. Im 18 and of course do porn, gay porn I have been doing for 6 years. Its more than just masturbating to anything. I actually like what I see in gay porn and how its presented. The men in the videos seem to have fun, I like penis, men's a s s e s and the figure of regular guys and fem gays. Also men are really good at kissing each other and the music seems to calm me down I am not into the whole muscle man thing. So I think I am expressing my homosexuality through porn. Because I am afraid of dating a man in public. I dated this really hot guy 3 months ago but let him off because I couldn't handle the pressure. All I want to know is, how come I am peaking high with homosexuality but my heterosexual side is weakening. I have been heavily homosexual for 8 months and im not that quite ashamed or mad. But I just want to know since I am an adult, if I might stay gay or something? I love women. everything about them I love. Its hard to focus on them now, because I am so attracted guys more than ever then I was say 4 years ago. I also want to add one more thing, they say porn can obstruct your mind and hange the way you way you find stuff attractive. However would it be different if I found gay action instinctive rather than making me like it. Because why would I be doing it for 6 years. I need help on how to break the awkward barrier on gay dating. If I can do that, I will feel more free. I don't wanna be a one night stand guy. I want to marry a a woman. I give thoughts about marrying a man, but it seems like I only want men for the sex. Don't get me wrong. Guys are great to be around. I just can't picture myself in gay marriage. But whats the point in marrying a woman if I have this gay stuff in my head?
