bisexual guy at uni, unsure what to do about it

I've known I'm bisexual for quite a few years but only accepted the label of bisexual this past year at uni.
I've told no one, not family, school friends or uni friends.
I have no idea who I should tell first or how to go about it. Most of my close friends would accept it, I have no idea if they'd expect it. However, I play rugby and I doubt they'd be as accepting, I wouldn't be banned but the comments etc. during socials and on training would be hard to take.
As you can probably guess I've never done anything with a guy, I've wanted to many times especially when going out.
I'm not exactly sure why I made this thread but I just needed to get it off my chest.

The main and most important part of all this in my opinion is that you do not need to worry about publicly telling everyone you are bisexual. I don't know if it is just me, but its a pet hate of mine that people should have to "out" themselves. A heterosexual does not need to shout out loud "I like vagina! I like vagina!", therefore neither should a gay or bisexual person have to shout the opposite. Just take opportunities you personally want to take, know your boundaries, and don't feel like you have to make a public announcement about your activities.

So you think I should stop thinking about hiding it from people and just see what happens. If I meet a guy I like I should go for it and tell people after, when I have more confidence.
No its not relevant to the game but the socials side of things is what I'm more worried about, they're not exactly the most progressive of types and alcohol doesn't make them more accepting.
But I think having accepted it and got through first year I'll see what happens next year. If something does happen with a guy (which I hope it does) I'll take reactions from there.
When you came out recently did some close friends know already?
