Sexually bored and frustrated

The guy I am with he’s a good guy he’s sweet and polite but sexually he’s boring me he only just wants to do the same thing. He’s all about anal sex (I personally don’t like it, but I do it to please him). Here’s where the frustration cones in I feel like I’m always on the short end of the stick because he never wants to do anything I suggest but he expects me to do whatever he suggests and if I disagree he gets an attitude. It annoys me to no end and I’m just bored with him and I don’t get anything out of it. 🙄😡
