I understand your concern about possible effect of masturbation on body height, breathing and weakness. Just as sexual intercourse cannot lead to weakness, short stature or breathing difficulties so how masturbation can do it? Masturbation is akin to sexual intercourse. What penis does in vagina during sexual intercourse, same it does during masturbation in your folded palm! This is a natural activity and I would say a healthy activity and does not either affect or deter sexual performance, height, or body structure. It is myth that masturbation causes aging, fatigue, bone problems and memory problems, weakness. Relax and go ahead. Wish you good health. </s>
