I bought this in order to add some spice into BDSM play with my husband and I loved using it on him. It looks stunning and is so smooth it slips in very easily. We found the best combination was with a cock loop or an anal electrode and the sensations were very strong indeed.
I made the mistake of getting the small instead of the medium but it works none the less, measure yourself guys. I have even used it on myself so you could just call it an electrosex urethral plug.
If you are looking for a great way to add some spice to your cock play then this is definitely worth a go, it's just like sounding but with the added sensations that go with e-stim play.
