Lots of good advice here that I won't repeat, but just wanted to add something about the kissing concern. Where you say,

"And then there's the fact that I haven't even kissed a girl, ever, so I would have to avoid that if things go intimate."

Dude, don't stress. And DON'T avoid it. I kissed a girl for the first time WAY after all my friends and I used to worry so much that I would suck at it etc, but if feelings are there, it just doesn't suck. Even if you're a bit awkward at first. And you learn QUICKLY! So just take it slow and don't force anything, so that when it happens, kissing, sex, whatever it comes to, it's not something that you're "achieving," it's just happening cause nothing could seem more natural and beauiful. You'll be fine man!! Conversely, I've kissed girls that I wasn't that into and it was just spit and breath and not that cool, even though we'd both kissed many time before. So it's got little to do with technique and more to do with what the kiss means to both of you.
