LOL Oh my God Robert. Fucking get it! I don't think you need to have a "gay experience" such as this to be officially "gay" though. Like, you just know! But good for you, even if this story is a little lolz-y!
Sounds like a creeper/someone who just wants to get in your pants if he was kissing you and playing grabass with you after meeting him irl for just 3 hours :|
if both of the parties voluntarily go on tinder and both voluntarily meet up after having talked to each other, I really wouldn't consider his actions out of line or unexpected lol
