Penis size is not related to masturbation.
Your penis length is average, so you have
no reason to change that.
As far as the girth, I don't know of many
safe, effective, and natural ways to
change that. I usually recommend that
people stick with their natural shape and
size unless it is so extreme that it
causes pain or makes sex difficult.
Penis size is almost never as much of an
issue to women as it is to men. A lot of
men don't realize that not all women want
a big, long, thick penis. Some women like
them big, some women like them medium,
some really don't care either way, and
some women like them small. Personally, I
don't care much either way. There are
good things about a big penis, and there
are good things about a small penis.
