[TOMP][MOVIE] Film about a woman hired by wives to test their husbands’ fidelity

Looking for a movie I watched around the early 2000s.

The main character is a woman hired by wives or girlfriends to test whether their partners would cheat. She approaches the men as part of her job and becomes involved with them.

She also has a friend who works in the same environment. The film might have been an erotic thriller or low-budget cable movie with unknown actors. Likely released between the late 1990s and early 2010s.

Any ideas?
