Dear user, I understand your concern. I will try my best to address your concern about perceived adverse effects of masturbation on future sex life. Your doubts are genuine at this age as you are going to start sex life with your partner after sometime. The apprehension about partner satisfaction occurs to almost every man. We do see this in our day to day practice. Masturbation is similar to sex with female. What the penis do in vagina, it does same thing in folded hand during masturbation. Sex with female does not cause any health hazards so, how masturbation can do...! Masturbation does not reduce sperm count nor it cause erectile dysfunction. In fact, it is a healthy practice to allow our sexual urges to come out in normal manner. It does not have any adverse effect on physical appearance, penis shape, facial appearance and memory and overall personality. There is no need to undergo medical check up. However, you may get counseling by psychiatrist or sex therapist to clear the doubts. I hope this will help you. Al the best for healthy sex life ahead.
