My friend and I did not have any penetrative sex. I touched the precum on his penis and rubbed his penis for a while. After which I touched a couple of other surfaces e.g clothing, a shirt, the sofa, a bag etc. I went to use restroom 20 minutes later and touched my panties and vagina when I went to pee and clean myself. Prior to using the restroom, I used a hand sanitiser to clean my hands and my hands were pretty much dry after that. It wasn’t like soaking wet with cum. And I did not at any point penetrate myself with those fingers. Will the hand sanitiser be able to kill the precum on my hands? It was only 50% alcohol.
