This man smells

I been dating a guy for 2 months now and we recently started having sex. This is gonna sound disgusting but after sex my sheets always smells like poop. This time I put an old towel under us and I found stains after sex. I always go pee after sex so I did and I wiped to see if I accidentally pooped on myself but I was clean. This is kinda a deal breaker for me 😖😷 I'm dying right now
