This is the biggest complaint with women I have met about men. The rule: women cum first. This means eating pussy. If you want a blow job, eat her pussy first. An after you fuck her, she will usually need help. Gals, if you ask him to suck you off and says no, drop him and find a man who cares.
The romantic bi guy.
Stay horny my friend.
Okay, I was born in 1960. My dad told me never to even try eating pussy. I am ecstatic that i didn't listen to him. I would have missed out on an incredible part of making love. He was full of shit about eating pussy. Maybe he talked to my dad at some point, in which case psychotherapy would be recommended. LOL
Anyway it sounds like your guy is either self-centered and doesn't care about you as long as he gets to cum. I would suggest you get a vibrator, use it and tell him that until he is willing to give the same pleasure he receives, you will use your vibrator and he can use his hand, because he isn't in a one sided relationship.
