Well. I have been masturbating prone ( i rub my penis to a hard edge of a table or something) for almost 12 years now. After reading this site. I decided to quit prone. Its been 2 weeks im 21 years old male. since i have avoided any sexual activity. Today i tried to masturbate by hand for 20 mins and couldn't cum. what should i do? will i ever be able to cum. Plus i feel my penis is too skinny compared to others that i have seen in photos. I think maybe thats due to rubbing the penis tip to edges. please help
