First time user,glad I did. A little lube and in it went no problem felt great. What a feeling when you come for the first time a long stream of juice any woman would love. No discomfort wearing it in but does tend to come out a little, so the next step is a 10mm beaded plug. As they say size is the secret so try something in your dick before ordering to get the correct size for you. Had mine in all morning no problem at all but will take it out for cleaning. Thanks chain gang for your help and a top product.
