Sitting in your own cum?

I wouldn't do it personally because I'm a clean freak. Most time I masturbate in shower.

But I was out with ladies other night. We were drinking and helping with a house project. We were just talking randomly about random shit. My friend. Mention if you cum lot. That it's good to sit in it for little while. Now I automatically said no.

I'm actually curious if any of you do do this or if there is any type of health risk and reasoning behind it. She was pretty much claiming that it can help your pH.
