So there is the question , is it ok to masturbate 1-2 hours after jelq without cumming.And other question , why is so important not to cum .. after I cum my penis still stands full
I think there's a general theory that the hormone prolactin -- which is produced at orgasm -- tells your penis to shrink up. The time it takes from orgasm until the next hardon is the refractory period. Most guys take 19 minutes to overcome the prolactin and get another hardon. The drug that prevents the production of prolactin seems to eliminate the refractory period in men.
Prolactin also tells your body to relax and is one of the reasons many guys nod off immediately afterward. Women produce prolactin when they are nursing and they get a very relaxed feeling while doing so.
There is a drug that prevents the action of prolactin; it's called cabergoline, also known as Dostinex and Cabaser. The normal use of this drug is to interfere with cancers that produce excess prolactin, at a dosage of 2-6 mg daily.
The recreational dosage is .125 mg once or twice a week. At this level the drug seems to have no side effects, but at the higher dosages it is known to have side effects that can damage the heart.
I theorize that if prolactin production after orgasm prevents PE from being as effective as it could, then the recreational use of cabergoline could allow you to both orgasm and maximize PE gains.
