Hi,I am Dr. Shanthi.E (General & Family Physician). I will be looking into your question and guiding you through the process. Please write your question below.
Hi Doctor! I am 25 years old male. I have two questions 1. I have been masturbating by laying down on my penis and rubbing it between my body and the pillow since I was 15 years old. Does it pose any harm? 2. I often masturbate for prolonged and extended periods of time by leaning on my back. Recently I was diagnosed with haemorrhoids and anal canal narrowing. I even noticed that while I masturbate, my anal canal gets tight and spasming. Does masturbation for hours and hours (using start and stop technique) causes anal canal narrowing over a period of time?
