Sounds like you got a strong USP (unique selling point). In that... it works.
Start by testing your price at a LOT higher than YOU think its worth. Sounds silly, but IF the product works and people love it you will sell a shit load anyway - IF THE SALES MESSAGE IS SECOND TO NONE...
You need somebody that could sell sand to the arabs, with the written word... If the quality in the product is there as you say it is... offer a full money back guarantee and the usual stuff.... and you will make lots of sales and still be able to payout good to your affiliates.
I'd love to know what it is, porn is not my forte, but what you are talking about is. ( I don't expect you to divulge any info, but it is interesting).
