Others have turned to Janet W. Hardy's 'The Ethical Slut', 'The New Topping Book' and 'The New Bottoming Book' - for advice on the most challenging questions of sex, polyamory, kink, and self-identity.

But Janet had to make it up as she went. How did she do it? Well, as you might expect from the co-author of 'Sex Disasters... and How to Survive Them', it hasn't all been roses (or thorns for that matter).

Here, in IMPERVIOUS: Confessions of a Semi-Retired Deviant, Janet takes you through the five twisty stages of her own kinky life - mirroring those of any good scene - negotiation, warmup, engagement, climax, and aftercare.

Delicious (and surprising) details await you inside. Bon Appétit!
