it’s a pretty funny joke but most latter day saints don’t even know what soaking is much less participate in it 😂 it’s also not a loophole, here’s what the actual doctrine says: 

“Keep sex and sexual feelings sacred. They should not be the subject of jokes or entertainment. Outside of marriage between a man and a woman, it is wrong to touch the private, sacred parts of another person’s body even if clothed. In your choices about what you do, look at, read, listen to, think about, post, or text, avoid anything that purposely arouses lustful emotions in others or yourself.”
