I don’t see any O rings large enough to go around that monster and be harnessed could it be a mistyping copy and paste from another product? Best to contact customer service and see what they recommend.
It looks like it’s designed so that the O ring sits in front of those small ‘spikes’ at the bottom. I guess you need a big O ring, and a harness that has straps to the O ring with a fair amount of play in them.
I usually use metal o rings in my harness but swapped to rubber and this was better and used the largest o ring - but it’s awkward and the dildo is not held firm
After looking I consider it’s a listing error and it’s non compatible with a strap on - as I noted that the unicorn dildos that do work on a harness - they don’t mention you can use in a harness
I thought so too. Creature cocks sell their own strap on kit, all with one rings.
Your dildo looks ill designed for strap on use. I dint think lovehoney sell suction plates, sadly, but the few ones I’ve seen are much cheaper than your dildo, so I would try that 1st.
How is the dildo’s suction? If strong, it should work well with any suction plate.
