ahhhh-mazing!!If you're looking for something a little more realistic and on the slightly "bigger" end, give Johnny a spin. If G-spot stimulation is important to you, he's your guy.
Johnny's use in a harness is great and simple for me. We prefer the SpareParts Joque harness which allows for up to a 2" inch diameter dildo to be used. Johnny is a bit of a tight squeeze, but it's worth the effort to at least try it. As far as how it feels in the harness to the wearer, it feels like a true extension of one's self as opposed to something dangling off of you, which is something that I regard as very important. Highly recommended. Of course, you can only use water based lube for this silicone toy, but it only adds to the pleasure. It's incredibly easy to clean; antibacterial soap for quick clean ups and boil friendly for a nice, thorough cleaning. When not in use, be sure to store it in a dry place. I recommend a light coat of corn starch to keep it healthy looking and soft.
We have used other silicone dildos in the past that weren't as "forgiving" in pliability and ended up on a back burners due to them causing some pain. The slight curvature of Johnny doesn't cause any pain according to my girlfriend, which is always a plus. The girth is just right in that it's slightly bigger than ones we've used before, but not so much so that it is an incredibly noticeable and "uncomfortable" difference. Noting the size, however, I wouldn't recommend this dildo for beginners as it is larger than average, but really, it's all about being adventurous and trying everything at least once... or twice.
