Did he hurt his hemipenes?

I had a male in with a female which was in shed because usually males lock with shedding females well.
They locked. Today, I checked and is seems the female shed DURING the lick, possibly, and there is some blood on the shed skin. I know there is a bit of blood sometimes but it is more than I expect. How can I know if the male hurt the hemipenes?

I got scared one time because my male peed blood after shedding. Sometimes they do that, I've learned, and it is nothing to worry about unless it happens constantly and not always when shedding

why do they lock well with shedding females ?

No idea paul. As I am not super experienced, I just listen to more experienced people who say they do. Maybe the girls smell different?
