Dear user, Thank you for writing to Healthcaremagic. I read your concerns. I could help you in better way if you would have mentioned your age and duration of problem. Penis shaft contains spongy tissue and it does have little curvature. Curvature becomes more prominent when penis is erect. Hardly man has 90 degree erection. This is perfectly normal thing. Masturbation does not have effect on penis size or curvature. Curvature has no effect on sexual satisfaction of partner. For example, if one has to pass inside a room through the window, it does not matter the direction of entering the window. It’s ENTRY followed by to and fro continuous movements that is important. Right testis is normally little lower then left one. No need to worry. Pain, swelling and tenderness are unusual and you should see general surgeon for this. Masturbation itself is a healthy part of sexual enjoyment and does not have any adverse effect on health. It does not cause weight loss (thin body), gastro reflux, and emotional problems. This is suggestive of anxiety about masturbation. You may have a talk to counselor or sex therapist/psychiatrist. These are not alarming situations. Just relax and do not become apprehensive. Wish you good health.
