A Pain after.. "Male Venting"?!
Question: A Pain after.. "Male Venting"?
Answers:
You're right, we all do it and it's nothing to be ashamed about. It's completely natural.
The part that connects your head to the shaft is called the frenulum. If you were not circumcised, it would connect to the foreskin. It is very sensitive and can get irritated easily.
It sounds like you are just being too rough while you are masturbating. Even tho you are using body lotion as a lube, you still need to be careful. Body/hand lotion absorbs into the skin, so you have to reapply it during your "session".
Take some time off from masturbating and let yourself heal. Then use a little more care with your body and use more of the lotion, or get yourself something better to use that won't be absorbed so quickly.
Hope this helps you man. Good Luck!
personal experience and reseach
You could be having a reaction to the perfume in the lotion. Try one that has little smell.
