I'm a male, I had tried this a couple times when i was younger not knowing anything about this site and i only made it about 2 weeks. So here i am now seriously attempting this feat and i am single which can be tough not having support of a partner. But have made it to about 1.5 weeks so far, not much i know but i think i may have some advice that may help others. I have given myself a few rules to follow.
1. Avoid contractions as much as possible, without contractions it's much harder to have an orgasm.
2. Avoid touching/toys on your self parts, if your not touching or toying with yourself you will not be very aroused.
3. Avoid porn, porn will lead to artificial arousal through contractions leading to masturbation, and orgasmic thoughts of sex, which can be very detrimental to your goal.
I will confess i do think of intimate thoughts of karezza, however i still do not touch myself although i rub my pillow a little bit, and i try very hard not to have contractions i still have some here and there, it's hard to try not to have contractions. Is it bad if precum leaks out? I want to try to build up my energy. Do females have contractions like men do that artificially arouse them and push them to orgasm?
