Most important thing is to be ready yourself. And you're right, you don't have to ever come out, but hiding yourself can be hard sometimes. I had difficulties to actually get the courage to tell the first person, and it caused so much distress so I just dropped the idea for a while, and let it "bake" in peace. Stop worrying about the solution, relax, and sometimes the solutions just pops up to your mind
And after coming out, my life didn't really change at all, I just have more sex
Well I also feel bit more whole maybe, more honest to myself, more in control (don't let other people opinnions rule you), more relaxed, but not that much
