yes my gut says this is related but not sure how exactly its playing a role.
i have experimented with nofap and fap and no finish for years and never ever had anywhere near the ability to stay near orgasm for 5 min. so i know 100% that effect came from diamond since diamond was the only knew ingredient.
but it is possible that diamond only gives this effect when combined with an extended period of masturbating without finishing like i had been when i got the effect.
im hoping that is not what is going on because then its less useful since i do not like doing fap with no orgasm for more then 3-4 days as it makes me too horny and i literally cannot do anything but think of sex. i had been masturbating without orgasm for 13 or 14 days when i got that effect so if that is what diamond needs to give that effect then its not very useful as ill very rarely have the time to spend 2 weeks in such a state of extreme horniness where i cannot work or do anything but think of sex.
for now i have moved on from diamond and bought sex mastery and testing that now.
