I have this air looking bubble on the foreskin of my penis. its kind of embarrasing. i have had it since i can last remember and im not sexually active. i am 16 years old. i don't want to pop it because i don't think that will help very much.

You : You state in your post that you are not sexually active however you state the "bubble" is embarassing. I will assume you mean you are embarassed to show it to someone like a parent or doctor. Honestly you need to have this looked at by a medical professional, and hopefully you will be reassured. Doctors examine patients all day long, including their private parts. There is no need to be embarassed. Good luck.
