It's not that he didn't realize it, he didn't know. The OP said that her husband doesn't even touch snakes with his bare hands so I'm sure he's not very interested in knowing about them (which is perfectly fine IMO).
It seems like the it's the OP's hobby and the husband is putting up with it and merely trying to help his wife.
Anyway, I would prepare to be a mommy just in case your bp does get preggers but I really don't think that one encounter will do it.
