Usually we are good, sexwise, bit's becoming apparent something is off this year. She thinks the issue is poor health which is probably a component, especially in past sessions but tonight I was getting increasingly frustrated and just didn't speak up. I don't know where to turn to for advice on this. Essentially I was doing all the work, I had two tuga on me and that was it, I was on top first and she was literally just laying there. Hardly making a sound. After that she told me she wanted to be on top so we switched and she was dry and I started to instantly deflate. The culmination of it all just sucks. When I expressed how I felt like she wasn't really reacting and enthusiastic, she lashed out at me and said it's because of my health.
I dont know, maybe she's right but I just was not getting the right vibes and I was feeling increasingly frustrated. How do I approach this better?
Great advice! A small bit of extra advice from my own relationship is focusing on talking about how things make you or her feel. And remember in this that feelings are never wrong, but can be misguided by (IE) not knowing the full picture. (Though never just assume thats the case for someone else)
Your feelings are valid OP! But, hers are as well. Try figuring out what's making you both feel unhappy about your relationship/sex life.
