Should I come clean about my life?

I'm almost 24 years old, I'm pretty sure im bi (pretty much gay though), but heavily lean towards men and would only date men, maybe only have with a girl if I were really physically attracted. I've never been in a relationship with a guy, and have had only three ual experiences with other guys. I was in a fraternity, I'm not your stereo-typical gay guy...pretty average dude, and im pretty sure it's not obvious at all, and because of this, most of my friends are straight men. I have a few girl friends but mostly straight mean. I'm afraid how they will act but on the same note I'm pretty sure they might not because my friends are either my frat brothers or friends who i've been friends with for a while. At this point, I honestly just want to come completely clean, come out, tell my friends and family and hopefully end my resentment of being gay once and for all. I think my parents would be accepting, but upset at first. So should I come clean and tell my friends and family?
