If a man masturabates on a daily basis (and that's totally normal) and
has sex a lot, usually the penis becomes "abused". When then hand rubs
the penis too much, the skin becomes darker from the rubbing.
The
above is completely wrong. This is not only for obvious errors such as
"a lot" and the misspelling of masturbates but the idea is just
completely wrong as well.
Skin that is rubbed too much becomes dry and chaffed, when this happens, people commonly call it skin that is "ashy".
The
penis is darker for no evolutionary reason. The technical answer is
that the skin of the penis has more of the pigment melanin than other
skin.
