I just received an advert for the penis patch. Featuring a tasteful image of a happy couple in bed, apparently about to have a loving kiss and a cuddle, all white sheets and bright lighting, this advert was probably (I didn't read it) offering a product that suggests it can extend the length of your penis if you simply wear some sort of hormone-treated patch against your skin.
They're marketing to people based on their insecurities about their bodies. They use idealistic imagery and centre it on an assumption that happiness is a penis the size of a small yacht.
I'm not convinced.
Mind you, if this patch did improve your sex life, it might also have an effect on your smoking habit. Either you'd be too busy to light up, or you'd increase your number of post-coital smokes (not something I'd know about - I'm a non-smoker).
And remember kids. Smoking in bed kills.
