That's very true. Archie is also "on watch", but I've checked out his rear end especially carefully and he still doesn't seem to have anything amiss or any signs of blood either around the cloaca or just inside if I lift the vent scale.
Anyway, he's getting at least a couple of weeks "off duty", just in case. He'd normally be entertaining three different ladies but has already had one session or more with each. I certainly don't see the need to risk it.
