Thanks for all of ya’lls inputs. I agree with montoya143 last post too. I haven’t tried the caps but I cut 3 or 4 inches off of the end of a penis extension and rubber band it to the mouth side of the receiver doing almost the same as the cap. I tight entrance with a lose grip length ways seemed the best for me. I think I am going to order the sleeve an give it a try. Why not after 1k on the product, 11 bucks isn’t anything.
