18 years as a plumber.I have been chased around the house by some pretty scary ladies(twice).These women were not desperate housewives though just desperate and perhaps a bit psychotic.Never have I been propositioned by a housewife or girlfriend.They might flirt a bit to get a smaller bill but that's about it.
It is not uncommon for a wife to wait till the hubby is away before calling a pro to do work in the house.IMO this is just so she can have the job done without resistance from the husband.
I think/hope this thread was started tongue-in-cheek?
