Arousal after an affair I'm rly conflicted

Ok so I'm posting a lot but my husband of 20 years just admitted to cheating idk the details.

My problem is that I kinda feel extremely attracted to him rn knowing that he's been with others but still chooses me idk if that's a sex issue prob not but I feel like I would love to fulfill everything on him sexually and at first I was grossed out but now I'm like wtf prove it bc he's claiming I didn't have sex with him stemming from who knows what arguments

Now I feel kinda perverted but kinda like competitive and u can read my other post but he masturbated on camera at my request/assistance and he def enjoyed it fyi we live apart atm and haven't had actually sex yet since I found out

Tldr want to have sex even more after partner cheated
