Porn is essentially showing wasting of pregnancy fluids
by men and women. When you grow older, men produce
less so getting a girl pregnant for you getting
children becomes a big problem to many. Now, it can
be a entertaining activity when you are young to
play with your pregnancy fluid (semen) in your balls,
and not letting it escape out and extend the session
thusly, but when you have grown a little bit more
it is important to find a partner (hopefully a woman)
and add your pregnancy fluid with HER pregnancy fluid
and create baby.
