Is masturbation safe. Pl guide me.

You are 29 already and you have been masturbating since age 15-16. Nothing has happened to you till date and stay rest assured that notthing would have in future too. Post marriage, with a good sex life your need to masturbate may reduce. Masturbation is a part of normal sexual growth and maturity of an individuals sex life. Early ejaculation that you ate talking about, need not worry. Make sure you educate your self a little more on the good techniques of sexual performance so that you do not ejaculate too early. If post marriage you still face the same problem and as a couple you feel it needs to be corrected then visit a psychiatrist/ sex therapist and they will help you. Do not anticipate so much and get worried.
