hi im a 20 year female, suffering from PCOS never fallen pregnant with my periods being regular every month. i just had sexual intercourse a few hours ago and it felt amazing , like it never has before felt that amazing, i was on top of him and i was sort of lifting my body upwards each time, and out of no where i blacked out and my head dropped and i felt that i was passing out, at the same time my arms felt really weak and i started coldsweating, i felt my body shake and my hands shake and i stated crying... my fiance made me lie down on my back but all this lasted about 1.5 minutes... what does this mean? also i some times feel no pleasure, a little pleasure and some days it feels extremely good like today, why does this happen?
