Just start doing those things now if you want to see what might be missing, you're only 27.
I'm 28, came out at 19, fucked around ever since. I have zero gay friends, I just prefer the company of straight guys, too much sexual tension with other gay guys. Been to a gay club once with some colleagues after work. Been to a gay bar once because my ex took me there. I just have no interest in those scenes. Do what makes you happy. Follow your interests. You don't have to engage in certain activities just because you see other people doing it.
