Too much sex

My (36m) wife (34f) wants to have sex all the time. I never thought I’d say this, but I’m just turned off. I don’t say no. I want her to be happy. So we have sex everyday. Now she’s telling me she wants more fore play and introduce toys. She told me she feels embarrassed that she has to take initiative. I sit there...in horror when she brought up toys honestly. Then I say, “Go ahead honey. Let’s try it.” Just to please her.
I don’t know what happened to me. I’m turned off from kissing because I think about the bacteria. I hate the smell of sweat and biological fluids. Obviously it feels good, so I close my eyes and try to focus on the feeling.
I want to please her and make her happy. What should I do?
