Can I be serious now?
Men have a refractory period between climaxs. You can't go repeatedly in a very short amount of time. Need to make more sperm/semen first. Plus the feeling changes from pleasure to pain to prevent you from continuing and maybe doing damage to yourself.
Apparently women don't have this, hence multiple climaxs. Theirs also serve no major purpose and need no extra ingredients made, so they can go again quite quickly.
That or padmedog really is just tugging his todger too hard.
