I've been talking to this guy a lot latley and I told him I liked him and he responded with that's sweet and I wish I felt the same way but my emotions are ed and I just got screwed over and I don't know how I feel but id love to hang and just see what happen. But a day after he said that he started texting me and was like we should do and I said I would give him a blow job in all then he was like ill pay you back and then he was like asking for nudes and asking if I was a virgin and things suddenly got really awkward for me and were suppose to hangout and I know he will want to have sex and I'm 16 but I'm just really nervous and I feel like I'm going to screw things up and he won't like me anymore and I just don't know what to do :/

First of all, don't just give your virginity up for just any guy. And don't give it until you're ready. Second, how old is this guy? In certain states, the age of consent is 16 but I don't know all of them. And honestly, this guy just wants to have sex with you. I don't know you personally but I feel that you're smart enough to say no to this and realize that this guy is no good for you. It's not too often to find a 16 year old girl who's a virgin now a days but those that are have their heads on right. Sex isn't something you "just do". It takes two very responsible and mature people. There are other guys out there for you just leave this one.

Why are you talking about giving a guy a blow job? No wonder he is talking about nude pictures and sex. You put it all out there.
Don't go out with the guy. He has already showed you what is on his mind. Sex, not getting to know you. The guy has no respect for you so worrying about him not liking you anymore is useless. Forget about this guy.
In the future be careful about what you say to guys. Giving blow jobs doesn't do your reputation any good.

As soon as he gets what he wants (sex), he will be gone. Say no and don't budge from that. He sounds like a total jerk.
