Urethral stretching is a stimulating practice that takes place in the black area or in role play in the clinic. Dilators (I use my own Hegar dilators) or urethral vibrators are inserted into the urethra. I use sterile instillagel for insertion. Water-based lubricant is used for those who do not like instillage oil.
The general use of sterile material goes without saying. Here I personally use purely medical metals (no silicone/plastic). Urethral dilation is not only used to increase a man’s sexual pleasure and is not to everyone’s taste.
