I'm writing a story that involves the use of a medical vibrator (specifically, the Ferticare 2.0) on a male patient to acquire a sperm sample and wondered if anyone here has any experience with such a device i.e. what it feels like in use. Obviously a rather personal question but it would help the story. I have some experience with non-medical varieties but I understand the medical-grade versions are much more intense. Any help would be appreciated - Stuprator
