Fiancé won’t stop picking scabs

I’m beyond annoyed with my fiancé cause he keeps picking at his damn scabs. So now I told him he can’t have sex with me since he keeps picking his scabs. The reason why is because I don’t want his fingers inside me.

He also gets his blood everywhere 🙄.

Edits:

He washes his hands but he doesn’t wash under his nails very good. Even if he washed his hands it’s still a no.
