don't mention it to the SO, because some day the SO is going to be watching dateline and see a story on how legitimate looking SPAs are offering extras.
That just happened in Austin, a place that only advertised in the therapeutic section got busted. Now this place advertised hot stones, face treatments and did legit massages, listed their RMT license in the ads but foxnews, local news all the paper tell the rest of the story.
Best option save cash until you have enough and go somewhere like Paradise and park in the back or somewhere else where you can park and not be seen, and don't mention a word of it to anyone. Discussions around a woman touching my naked body is a discussion I do not want to have with the SO because the conversation will eventually get you jammed up, did I mention her girlfriends will get her stirred up to "where is your husband" and she says "getting a massage" then the conversation goes "I have heard about those places" and you get the picture.
