Like a FitBit for your penis, this hi-tech cock ring not only monitors via the app, your vascular blood flow when you’re fucking but also at rest, even during sleep. We all know about nocturnal emissions and erections and now the Firmtech ring can tell you everything you need to know about your own penis health. MyFirmtech.com
