Confused.

Ive been hanging out with this guy for a few months and we’re just hooking up. We haven’t established what we are. Neither of us have done anything like this before and I’ve given him a couple blow jobs recently but he doesn’t reciprocate. He offers lots of times but when I say yes I can tell he get really nervous and never does it because the moment fades away. He also doesn’t like to kiss after I blow him. I’ve talked to my friends and they say it’s normal but it kind of upsets me that he doesn’t want to kiss me after. I feel like I’m being used but on the other hand I feel like he’s just nervous to do that stuff with me since he’s never done it before, but I’ve done stuff to him so it feels very one sided. I’m planning on talking to him and establishing what we are because I’m very confused. Any advice? Any thoughts on his behavior? Help a girl out
