No one wants to promote you say? Why Not?
I give you a clue "We sell lube condoms enhancers pumps and more" Its not that appealing.
Your products are cheap, so an affiliate would have to sell vast amounts at 10% rev share to reach the $50 payout. There are much better and easy products to promote out there. Plus in my experience promoting stuff like this is easier with a whitelabel solution to add to exsisting adult sites, which is what I do. Maybe look into that side of affiliates.
I would say whitelabel is the way forward.
Just my 2pence.
