Hi,I am Dr. Shanthi.E (General & Family Physician). I will be looking into your question and guiding you through the process. Please write your question below.
I am 18 and I just realize how to get my penis head out, after that I tried to masturbate but every time I got hard the head really hurt and I can not masturbate. so how do I solve that problem, or is it some kind of infection or anything and my other question is how do I get my penis bigger in size?
