I have a question: some clients engage in '10' with the therapist during OOO.

But condoms must be used with a water-based lubricant; oil-based lubricants can easily cause them to break.

So are the massage essential oils that shops generally use water-soluble? Or is doing '10' at a massage parlor a very risky/dangerous act?

(It seems like the massage essential oil is already smeared all over the penis, so it’s unlikely they would wipe it off and then separately use KY lubricant, right?)

I hope someone on the forum can clarify—thanks!
