Why you lost your lust so fast?
It is probably because of oxytoxin that are created in your brain
as you enjoy. It is just like any drugs that gets you high, expect
that this is natural and is healthy, as long as you don't overdose
yourself. Moreover, this chemical relaxes your body, tiring you in
the process. So, I probably suspect that your body and your brain
are relaxed and are not thinking as hard as you had before
masturbating yourself. Anyway, the buffet example is good enough
for you to understand.
