This uncommon thing just happened to me twice. I bled during sex, without pain, and I'm not close to my period yet. I'm 21 years old, and have been active since last year December. Although not often.
I had been diagnosed with Polysistic Ovary Syndrome last summer, but the cysts I believe were gone. I'm also on Birth control pills due to my LOW estrogen levels and being sexually active...
MY question is, Well, obviously, if I haven't bled this way during intercourse before, What could be the reasonsi have these past two times?

Not enough lubrication ? Too rough ? Medical issue, not known ? Sorry without knowing more it is hard to say

Trust me, the lube isn't needed, Friday might have been a bit rough, but not today and I still bled. The issue is the bleeding During sex. I'm healthy, never been pregnant, I just had hormone problems with my estrogen levels and cysts in ovaries last year.
