It depends on the bloke. Some hunky twenty five year old would be fine. An old bloke with a hairy beer belly is another matter.
It wouldn’t bother me in the least because I have this thing called a neck and these items called eyelids so I don’t have to look if I don’t want to.
Mind you I’m in Florida so that means that a) we are more casual than many other places and b) I’ve sort of seen it all by now.
