Yes. I’ve done this with a regular masseur who was comfortable with a lot of mutual body contact and it was a fun change of pace. In my experience, many masseurs love getting good massages themselves, so I suspect you would find lots of interest in this, especially if you have solid technique. You definitely want to discuss it before so the provider can lay out boundaries, and discuss pricing and how long the session might be. 90 or even 60 minutes can be a LONG time for an amateur.
