First I'm going to get this out of the way and agree with everyone else: drop this guy.
You're two days into a "relationship" and it already sounds like a toxic one. Obviously he doesn't care about your feelings, so he only deserves the same in return, and it'll be far better for you if you get out of this sooner rather than later. Do it over the phone or through texts if you need to -- normally I wouldn't say that, but given how this guy sounds my usual reasons don't apply: just get out of this.
Second, you really should go to Planned Parenthood and see if they can give you the morning after pill or not.
Third, I think you already have your answer on your sexuality. If you have no interest in other guys, and only "drool" over girls then obviously you're straight. Sure, this might change in the future, who knows, but for now you have your answer and as others have said it's not really a pressing matter that needs to be figured out right now.
Fourth, and don't take this the wrong way because I'm only trying to help you out, you really need to gain some self-confidence, man. I know it can be hard when you're young and trying to figure things out, but sometimes "faking it 'til you make it" does work, and also sometimes you have to force yourself to do things in order to gain the confidence. Start working out or something, or start a sport that will help you with self-discipline and self-esteem (boxing and martial arts are highly recommended). Sometimes music can help as well. Do things you enjoy and work on feeling comfortable with yourself and the self-confidence will build.
I know it can be difficult feeling comfortable with yourself given the whole trans thing, but you don't have to be 100% comfortable with your body to be self-confident. This is more about feeling good about who you are personality-wise and stuff, feeling confident in your abilities so to speak, than it is about saying that you love everything about yourself. Does that make sense? Sorry if not, I've been sick so I'm trying my best.
But, really, self-confidence is key in so many things. Life can really take off and things can really happen when you're self-confident that you might miss when you're not. Plus, you don't end up in nearly as many bad/potentially bad situations.
Good luck. I know you're young, so take these as the words of someone who, really, was in the same low-confidence position not that horribly long ago.
Compromising yourself gets you nowhere: you need to stand your ground on things and, really, put yourself before others. They're responsible for them; you're responsible for you.
