I'm a 27 yr old virgin, I am morbidly obese & I have possible PCOS (although my doctor does not want to do an internal ultrasound due to my virginity). I have had my period now for about 4-5 months with maybe a 1 day break in between. I have been passing large blood clots and this causes my s.towels to be soaked. I have noticed that after I maturbate, as my periods appear to be finishing/finished, they come back heavily the next day for weeks-months. Why is this?
