I started masturbation at a very young age(16 to be specific) and with the passage of time, my erections are now getting weaker and softer. I get lot of pre-cum(even watching a sex scene in some Hollywood movie results in a drop or 2 coming out). Also I ejaculate much quickly then before as I feel my penis is more sensitive now. My penis size and width has also decreased a bit.
I would like some doctor to thoroughly check my penis and prescribe the treatment. Can anyone suggest me someone?
