The anonymous woman said her husband began using prostitutes after discovering poppers, a sex-enhancing drug

A wronged wife was forced to undergo a HIV test and was driven to self-harm after discovering her husband of 30 years had been having a five-year 'affair' with one prostitute.

And after wringing the truth from her lawyer husband, the anonymous woman began charging her husband Sh5,700 every time they have sex, the same price he paid per session with the prostitute.

The woman is demanding codes of conduct are implicated at brothels masquerading under the guise of spas, to stop sex workers monopolising one punter.

She said had her husband "screwed a few here and there" she could accept it better.

"Why the same person?" she asked, when speaking to the Sunday Mercury.

"The fact that it was the same person, that really does bother me. That is the main betrayal. If he’d screwed a few here and there I could accept it better - it would still be devastating, but I could accept it better."

The high-flying professional in her 50s said her husband admitted his 'affair' with the prostitute began after he discovered poppers, a sex-enhancing drug.

And after finally discovering the truth, the humiliated wife had to undergo a HIV test.

To protect her children, the woman remains anonymous, but is referred to as 'Sarah'. “Thankfully, the test has been all clear,” sighs Sarah, speaking about the test.
