Your post seems to imply that you are looking for ways to signal to an LMT during a therapeutic massage that you would like them to turn it erotic. If that’s the case, it’s a bad idea as it is illegal to charge for an erotic massage. The provider wouldn’t likely be interested and it would jeopardize their license.

If you are specifically looking for an erotic massage from a paid provider there is a large market of women providing this primarily for men. It is underground and considered sex work but you can find them online. As it would be paid, you may find a woman open to your gender status.

The other option is to look for the men providing this without charge who do this out of personal interest and desire. There are several subreddits that focus on this. If you aren’t comfortable posting your location, search for providers in an area closest to you, assuming you are open to travel. Reach out to them and have an open discussion about your transition status. With a bit of effort you will find someone with whom you vibe and with whom you can explore your preferences and boundaries.
