If done intentionally, what were you hoping to achieve? What effects did you notice, both desirable and undesirable? Why did you end the orgasm denial streak? What did you learn from the experience? Did you do it solo or with a partner? Demographic details (eg, age, sex, gender, sexual orientation, relevant kinks), if you care to share, are also helpful to understand your experience.
Btw, I created an !orgasm_denial_psychology@lemmynsfw.com community.

About 2 weeks, had a boyfriend into the idea of Excessive Cum, and heard saving up made it so there was more, that and drinking more and having magnesium-rich foods
I can confirm. But specifically, edging for a long time, painfuly unable to cum, then finally cumming, leads to oh so much cum.
