Wash, i got no idea what your trying to ask.
I would punch a man dead in his left retina in he even tried to take a wizz in my kitty.<br />
Punched. In. The. Re-tin-a.
I wouldn't think that it's very hygenic.
Assuming the stars are aboiut peeing, it is safe and very enjoyable providing you are both happy about it and you have a douche afterwards. Its better if the man has had lots of water/fluids to drink during the hours before sex, then his pee will be quite diluted and weaker.<br />
Go ahead and enjoy!
