28 M, finally realising I might be gay and need advice

I'm not sure if this sort of thing is allowed here so I do apologise in advance if I should have posted somewhere else.I'm 28 male and finally accepting that I am gay, I've always thought of myself as a "closet bisexual" in that I've always been attracted to men but never really done anything about it since I always always worried about being "outed" so to speak. My friends are mainly made up of guys I work with, and while they aren't homophobic, I think they would offer the support I'd need letting everyone know.I've liked men since I was younger, but always put it down to wanting to experiment or just general teenage hormones, but the past couple of years I've felt like I wasn't attracted to women at all, I had no interest when my friends would try hook me up (I'm not a very outgoing person, I believe socially awkward is the term), but many a time when we've been out I've seen guys I've really liked, I've felt myself get aroused by men in clubs or just in the street.I'm just quite confused right now as taking this all in feels so stressful, all I can think about is "is this just a phase" and it's driving me crazy.I guess I just need to talk to people who have been through similar situations or just anyone willing to talk, I don't really have anyone I could talk with about these sorts of things.Sorry if this post is confusing or just doesn't make any sense, I'm kind of just writing down what comes to mind, it's taken a lot of me to even type this up.
