I’m a post phalloplasty transgender man so I got the Erektor to help Give me an erection until I’m able to get the prosthetic put in. This is a great product for trans men especially since most prosthetics only last 5 to 10 years and then you have to have another surgery this product can aluminate that. When ordering they give you lots of instructions on how to Measure and I still ordered the wrong size. I’m very grateful that I can reorder for only $100. Guys, it’s worth the money!
