38 year old male. My penis has shrunk in length and girth over last year or 2. I have lost nearly 1inch from 7 to 6 inches. And erection is not as hard nor do I last as long sexually.

Are there any answers or explanations or cures?

My history includes lots of masturbation and lots of sex with many women. Additionally I have been involved in bike riding and feel that maybe bike seat has contributed to size decrease.

I have heard of bike seat decreasing sensitivity(i do have some) but has biking also been linked with size decrease?

I did go to a urologist a few months ago and he said size decrease more mental than physical. He suggested it was mental as i am a "commitment phobe" dated lots but haven't wanted to settle down and get married.

I also seem to have a disconnect between my body/mind and my penis.

Additionally I ejaculate sooner than before and can not have sex more then once a night.

any help?
