(for straight people)
The object of the game is to go an entire month without intentionally looking at any porn. it gets SO MUCH better if you havent seen it in a long time. It's good for you . Anyway, if you intentionally look at straight porn you HAVE to cum while looking at hardcore gay porn. It is your punishment if you give in. (but you wont give in to the desire, now will you?)

Maybe we can see if anyone is up for the challenge?

hmmm

the only problem is
this site is full of porn
so you are asking someone to stay away from this site.

Or you can only watch porn if locked in chastity and must cold shower after every half hour

Actually, the concept of porn abstinence is intriguing. I've noticed in past denial series that the most challenging and frustrating part for me has always been whenever ordered to avoid porn - even for just a few days.
