I’ve noticed that since contracting PFS, my refractory period is essentially nonexistent. I can ejaculate multiple times without any discomfort in the penis. Traditionally men, as well as myself experience discomfort if attempting to induce another orgasm shortly after the first. I can do it multiple times without that corresponding discomfort. More curiously perhaps, the second orgasm is more intense than the first.
Scientists believe temporary elevated oxytocin and/or prolactin levels lead to the refractory period. Makes me wonder whether I’m not getting those elevations after initial orgasm…
I’m not sure what insight that casts, though it would be interesting to see if other PFS sufferers have experienced a similar situation.
