Hello doctor. I m 21 year old. I really have some doubts about my reproductive organ. I used to masturbate for the past 6 years and I do it at least 3-5 times a week. I really don t have control in ejaculation, it occurs within a minute after arousal during masturbating and sometimes its ejaculates in sleep by itself. My penis is shaking and pain a lot while doing it. And also am worried about is, the Outer skin is not getting down the penis head and feel its small to my age. Is this immature growth or is a normal one. Will these thing affect if i have an intercourse.??? If there is a real problem please suggest me a natural remedy. Thank you.
