Exmo Lex admits to soaking in this video:

It’s obvious BS. No one does it and any who say they do it are lying. Let’s stop talking about it.

[pointing to self] I did it. My husband and I soaked. Why do you guys think I know about it. Why do you think I know for certain it happens. Cheers to that embarassment. Yes, I know soaking is a real thing because I, myself, have done it. The reason people don’t admit to it is because it is embarassing as f***.

She didn’t know it was “soaking” at the time, but later learned the term associated with it.

In a podcast I was listening to several years ago I heard an LDS sex therapist refer to clients who had admitted “soaking” to them. I have not been able to locate the podcast.
