why do i ejaculate so fast after masterbation?

Thats called PREMATURE-EJACULATION which is a comment problem. This has developed and grown simply from the fact that u act with ur stimulations with a lot of aggression, u tend to race to climax without getting there. Also FREQUENTLY masturbation and doing it too much, will obviously create a hell of a lot of stimulation.

This isn't really a good thing. If u look ur first masturbation and ur last, u can see how long it took u at first. Normally, the fast production of semen, implies that it doesn't have enough quality, meaning that ur likley to have disrupted the strength of build up to ur semen, that would produce with enough amount of quality to enforce a child.

To revert back the normal time length, which would also indicate a more quality semen, u would have to take a HUGE time gap between ur normal sessions. For example stick to ONCE a week. U will notice a very strong urge to masturbate - which is perfectly normal. The longer u hold it back, the longer it will take and the MORE amount of semen u will actually release. Stick firmly to a big gap, that holds u desperate, that way ur waiting period will grow stronger and more tolerable and the amount of semen will have more time to fully develop. And try not be aggressive and race to ejaculate at the begging,take ur time and consider foreplay. Good luck.

Well if you don't want to, then whenever you start getting close to ejaculating, stop for a bit.

Just go slower in stimulation, and do it daily to reduce quick release.
