I think I've actually developed a kink for my own blood! I just love seeing it on a guys cock after we have sex, and smeared between my thighs. It's like a hicky or bruises -- so hot to take note of the passion that just occured.
Thanks for linking to my piece too! As a ps. to that relationship, the last time we had sex (right after breaking up... closure sex?) I was on my period. It was the first time I didn't worry about his sheets... ahhh it felt so good!!
