Pleasure him and I don’t receive

Al

Basically as the title suggests my partner is always up for me to pleasure him without sex but he won’t ever pleasure me it always leads to sex but now he won’t even kiss me doesn’t want sex but he wants me to pleasure him and it’s really knocking my confidence and self esteem I told him before and he didn’t really say anything about it or give an answer as to why he’s quite sexually selfish as I call it. I’m at a loss with what to do as taking to him hasn’t changed much and I didn’t get any answers from it.
