I had sweaty and smelly sex and I feel disgusted that I am not disgusted by it ...

I was raised by a woman (not my biological mother) who would get very upset if I smelled bad. Nothing in our house could ever smell bad or she would throw a fit. My wife is also like that. She is very personal hygiene conscious and a bit of a germophobe. Last week, we were working in our back yard. She was pushing the lawn mower and I was cutting overgrown branches. It was hot and we got sweaty. Then I started painting the garage and my wife also helped. The garage gets hot as it does not have any air-conditioning or even a fan. We were both drenched in sweat but the work continued as I was up on the ladder. By the time I got down, we were both very damp. She was wearing a white t-shirt / tank top and it was so damp that it was sticking to her body like a transparent second skin and I could see the bra and what it contained. For some reason I felt aroused at that sight. I asked her if she would have sex. She said it is middle of the day. I told her I am feeling aroused and she said it will take her time to shower so why dont we plan it for the night so that we could both freshen up. I told her that it is an urgent need and I do not know if I can wait. She asked me what triggered it and I did not know. I told her maybe it is the way you are exposed? She said "I am dirty." I told her "I am hard." One thing led to another and we ended up in our room where we had sex while we both smelled ... lets say not very good. The sweaty smells that people wear deodorants to eliminate were very obvious but for some reason they were mutually arousing??? it was sweaty, slippery, dirty, smelly, animalistic sex. Bodies feel different when they are damp and slippery so may be it was that, but she had 5 orgasms. I also experienced probably the most intense one. We showered (separately) but never spoke about it. How do you say to your partner, "By the way, you smelled dirty and I loved it!" Not sure how the other would take it. She never said it but we both knew we loved it. I am embarrassed and disturbed by it. Secretly, I must confess that I would like to do it again but I am so ... like I do not have the words to even admit it. May be I am twisted? Just a confession!
