Thank you kandjmom and nohard
Hi Ak, Well your just normal, your getting nocturnal erections are a thing that happens to us men, you dont need any drugs, and try not to masturbate to much, keep it to a couple of times a week this would br thenormal thing, its a nice way for us men to kepp the system ticking over till we start a good sex life, you erect size is OK your still growing.
The colour of your penis when limp will always be darker, this is because the skin is compressed, hence looks darker.
Hope this helps you.
Good Luck
Try posting this in the a erectile dysfunction forum. you will probably get more answers there.
it's probably your hormones doing that to you. everybody is different. as you get older you will get bigger. as for the color, every mans is always a little darker than his skin color.
