Tracey Cox, Britain's best-known sex guru and presenter of Would Like To Meet (BBC2) and The Sex Inspectors (C4) just popped up on GMTV to promote Amora, a high street sex academy in central London.
If anyone else had been behind it, I might have been concerned about its aims and integrity, but Tracey Cox is the most respectable and respected of sex and relationships experts - and without her, I would never have begun dating at the age of 41 or met my wife.
Tracey was one of my three tormentors on Would Like To Meet, the intelligent dating makeover programme in which she and two other experts, Jay Hunt and Jeremy Milnes, pulled my life apart, sniffed at the bits, then put them back together in a rather better order.
From someone who hadn't even been out with a woman (or anything else) for 12 years, and was still not sexually active at 41, Tracey helped turn me into a man who is now happily married to a wonderful, beautiful woman called Inda.
Incidentally, I have the rare distinction of being possibly the only person in the world ever to make Tracey Cox blush.
As she's written numerous sex books, including Hot Sex which has been a best-seller in 47 countries, and Supersex, it takes some doing to make La Tracey blush.
While filming for Would Like To Meet, Tracey sat next to me on the sofa in my front room and told me, on camera: "Don't worry, you'll be having sex soon."
As this seemed about as likely a prospect as a Martian landing, I told her so. But she repeated the claim and added: "In fact, I personally guarantee it."
I remembered this some months later when Tracey and I found ourselves both guesting on BBC Radio - Tracey in London and me in Plymouth.
I reminded her, live on air, of her promise that I'd be having sex soon and that she'd said she would guarantee it.
I asked her what the terms and conditions of the guarantee were, and Tracey, for possibly the first time in her life, was temporarily lost for words.
Fortunately, I didn't have to take up the guarantee after all, as my future wife wrote to me after seeing the show and we were married later at The Ritz in Piccadilly.
Which happens to be quite close to 13 Coventry Street, where the Amara sex academy is based.
You can find out all about it at www.amoralondon.com, but take it from me that if Tracey's involved, it will be informative, fun, and potentially life-changing.
