Don't forget to exercise the ol' PC muscle and you'll have
erections longer and be able to 'control yourself' for a
longer period of time as well.

Where is the PC muscle? Pretend like you have to take a
crap or a piss but have to hold it in. That's the PC
muscle that holds it in. It feels like you're sucking the
area between your cock and your ass to inside your body
when you exert the PC muscle strongly enough.

Anyways, practice contracting the muscle every day. Try to
do 200-300 contractions at a time. Nice thing is that you
can do it while sitting in the car, lying in bed at night,
etc. No one will know you're exercising but j00.

Congrats again for putting the hammer down!
