I have been the male in this exact situation before and it’s terrible. She gave head in the beginning enthusiastically every day. Then less and less until confrontations arose from me asking. It’s a rock and a hard place. You don’t want to give up a relationship you’ve invested in but also don’t want to give up happiness.

Receiving blowjobs is a crucial staple of my overall happiness. It’s like pretty much my favorite thing in the entire world. I can’t imagine a relationship or life without them. I don’t particularly like going down on my gf, it makes my tongue sore and I can’t breathe but I do it enthusiastically without her asking because I know she likes it and I want to make her feel good. Maybe you should look deeper into why you don’t feel this way toward him.
