When i was a teenager i started experimenting with post orgasm play and i figured out i can go for two, three, or more orgasms (with ejaculations) without ever going through a recovery period. i'm told that's not normal and do my question is, why?

It is almost certain that refractory period will happen after the ejaculation in men. However, refractory period, short or long, varies a lot among men. If you are able to achieve successive orgasms with ejaculations without a refractory period then you are an exception. Refractory period is just a physiologic response of your genital organ to the neurotransmitters' effects. Take care.

When we are young we can have multiple orgasms with ejaculation. As we grow older the amt of ejaculation diminishes with subsequent ejaculations and also the number of orgasms. This is part of aging
