What Causes the swelling in my penis after masturbation Last 10 years this are the problem Hi, I always get some sort of swelling in my penis each and every time I masturbate. I doubt if this is some kind of swelling due to excessive heat. Will the same happen at the time of sexual intercourse? I am still single. Will this be a problem in having a child after marriage? Is this a serious issue to be concerned about? Please help me out and suggest me with the necessary steps to be taken. Since I have the practice of masturbating, I notice this at all times and I am very sure that I always get such a swelling whenever I masturbate. This is disturbing my confidence of sexual life. Try to make each and every point clear.
