Yea it pretty much comes down to one thing..

The Decision.

Make it, and follow your plan through,

This doesn't mean you HAVE to broadcast it.
Alot of people fall into the "needy" mode where they have to tell EVERYONE even if its something we're NOT talking about. Those are the ones that are annoying.. Its like ya it aint new, right on, lets keep sexual preference in the bag of tricks until time to pull it out. And like chicky says just do it and be yourself. Thats who you are thats who you are.. No if you're bi then you're bi, but it sounds like you wanna actually tell em your gay. Which is cool too, but make sure you know what you are before you tell em what you are. Or THEN you'll have issues with people thinking things about you..

Got ALOT of gay friends (cali) , not gay myself, would I???

MMMM maybe if I was drunk enough... whew. Can't hear myself typing no because that would be a lie, I'm a wild guy. For sure not without female presence. Anyway thats neither here nor there.
Get yourself a brand new pair of nike running shoes, chew some valarian root and just do it mang. Be free from yourself.
