Hi all. i frequentky masturbate.. I am doing it past 10 years.. I used to masturbate while sleeping on bed.. Lying upside.. And rubing my penis to the bed for pleasure and fantasies in my mind I had a great time. But my penis is loose and shape has changed and penis looks bent,, So Recently I have changed and started masturating in Bathroom.. With my hands.. Please advice me whether MY previous masturbation type of ruing on the bed will cause hernia, or stone in intestine or piles or any such problems now or in future..please advise me the orret way to masturbate,,
