At times lately when I have intercourse, I find that just under the head of the penis on the underside I get a "splitting effect" of the skin. It seems that if she is not really well lubricated and she is on top that when pentration is attempted it "grabs and pulls the skin" untill it tears. It becomes an open sore either on one side or both sides and it is very irritating. It seems to heal in about a week and as long as there is plenty of lubrication I'm fine bit if she's not lubricated enough..OUCH! Has anyone else come across this problem before and if so how did you "fix" it?
