OK if you're not happy with giving extra services for VIP then I'd concentrate on playing up some elements of your current offering.
Get on YouTube and watch some videos about giving massage, ta-dah, you are now a masseuse. You're not advertising therapeutic massage so you don't need training - just advertise it as a "sensual full body rub using only the highest quality unscented massage oils".
Advertise that you use "the thinnest condoms in the world for the best and most erotic sensation".
Re-brand one of your current offerings, probably OWO, as something like "an experience that is totally focussed only on your sensation and pleasure".
FYI. Be careful what massage oils you use as some are not condom safe.
I would say that of my VIP customers, less than 50% want full sex anyway. I have designed my advertising to appeal to a service that is focussed on stress relief where they do none of the work.
