Returning the favor

Jordan
Me and my boyfriend have been dating 2 years. I always want to please him, so I give him a lot of bjs bc i know he really likes it. But he never returns the favor. In our 2 years he has only gone down twice. And it gets aggravating, bc I have been so nice about how he feels especially since I swollow to please him and I hate it. He gives me reasons on why he doesn't do it
1. The texture
2. Past issues that has happened 
I just don't know what to do
