but some state's laws that describe illegal behaviors include descriptors like lewd and lacisvious, so I think if LE wanted to bust a DIY provider they could and possibly get the charges to stick.

A lot might depend upon what the provider does or does not do, especially if she exposes her genitals or breasts as opposed to just wearing something sexy and doing a good voice over.

There was only one famous case of someone getting caught which involved, if I recall correctly, Jimmy Swaggart of TV evangelist fame.

I'm not sure if he ever faced charges from being caught, however.

I'm curious myself if this practice has ever been prosecuted.

(still not a lawyer)

My lay research suggests that DIY isn't illegal, but offering it is: (this is from an old post of mine)

The current debate (thread starting  http://www.theeroticreview.com/discussion_boards/viewmsg.asp?MessageID=151187&boardID=21&page=1   is suggesting that a hotel room, massage room, etc., are all public places and that the laws governing public behavior apply. Any opinions, make that "answers," on this board?

Has this been asked and answered (satisfactorily) before?

My older post:

Regarding "unlicensed complementary and alternative health care practitioners," it comes full circle back the same definitions as in the other ordinance that defines "sexual contact." The Statutes have evolved over the decades and contradictions are rare:

https://www.revisor.mn.gov/statutes/?id=146a.08

"146A.08 PROHIBITED CONDUCT.

Subd. 1. (d) Engaging in sexual contact with a complementary and alternative health care client, engaging in contact that may be reasonably interpreted by a client as sexual, engaging in any verbal behavior that is seductive or sexually demeaning to the client, or engaging in sexual exploitation of a client or former client."

The statute is more expansive than for "prostitutiion," but still not prohibiting DIY. When an act is intended to be prohibited, statutes tend to specify.

In practice, duh, extremely tough to pull off (no pun originally intended), but defensible if words were simply not said or chosen wisely, IMOH, of course.
