does your SO do this? TMI

Okay so after we have sex he washes "me" off his dick with a wet rag and water. I'm like jeez do you find me gross? He told me that if he found me gross he wouldn't be with me much less having sex with me lol 
He said that I get super wet and when we are done he has my disharge from sex guess you can say all over his dick and even down his balls and if he leaves it, it dries up and and flakes off. He said thats normal "it means that I did a good job" 
But still I feel like that's disgusting. 
Am I disgusting or does that happen to you too? Idk I just get extremely turned on by him and he is REALLY good in bed like my bad. Edit: I do pee after sex. But he doesn't cum in me, ever. He cums on my stomach or back and we clean that up, while I'm cleaning that up I wipe myself and then I go pee. I have to pee everytime I have an orgasm.
