I remember once donating blood to the Red Cross. I had recently ended a very steamy sexual relationship that had lots of orgasming with my first girlfriend, my first lesbian relationship.
When looking through all the criteria, I started wondering if I qualified to donate blood. My ex girlfriend was trans, and being poly she had other lovers who were men, who slept with other men. I started getting concerned, until I realized though there lots of orgasming, the sex we had wouldn’t meet the definition of sex by the Red Cross as there was no PIV or even exchanging of bodily fluids. So I guess as lesbians we never actually had sex! But don’t tell that to my very happy clit, and happy g-spot who left its own puddles or skee fluid on her mattress as a souvenir.
