I don't see this as comfortable for a man...it's really a female use toy. Once again, I refer to our Facilitator 1615-01-3. This vibrating strap on was specifically designed for men....the dong is a PPA, (prosthetic penis aid) slides over a flaccid penis. We also sell the Vibrating Latex PPA with with Pump and vibrations.. This also slips over a penis, and it inflates for more girth with added vibrations for both partners. Both of these items are built to hold a flaccid penis. The Facilitator has it's own straps, while the Vibrating Latex PPA with Pump works well with most harnesses that are readily available. For DP action, try our new Accommodator Dual Penetrator. We call it the ultimate dual penetrator. Worn by a man using his own penis and scrotum to stabilize the support, this hot new item is slim, comfortable, and life-like.
