Never kissed a guy/first kiss experiences

So, I have known, or at least suspected, that I am gay for quite a few years now, but have only started to accept that it would be ok. However, I feel like I can't really be sure until I've at least kissed a guy. The problem is, though, I don't know how I would go about doing that. i don't want to talk to my family about it until I know for sure, after all, and only a couple of my friends even know it. So, how do I meet someone? Everyone I've told is always surprised, because apparently I give off a "straight guy" vibe.What were your all's first (gay) kiss experiences like, and how did they happen?
