All males have erections when they are young. Sometimes when they
are not wanted . I remember having a super hard on once when I was in
wood shop and I was embarressed as others noticed my condition. As
you get older the day time erections are less and less and then it's some-
times hard to get hard,but there is the "PM" or night erections; an automatic
thing where you wake up with a stiffie. Does anyone know what is the
main reason for this? I know during the night ,you probably have not used
the bath room and a certain amount of pressure is built up....but is this it?
Maybe a Doctor could answer my question but I never think about this when
i'm in his office.
