Stretching

Anyone know how can I stay flaccid because I seem to get hard after a while.

Punch yourself in the nuts ;}

Over a period of time, once you get used to the feeling, you’ll stay flaccid. Maybe you might want to think about turning on the TV, and keep your mind busy.

Do inverted v stretches before your regular stretches. Remember, they are advanced but according to your join date your should be able to take them.
