The Stout Feeldoe is the largest of the strap-less Feeldoe strap-on dildos. Feeldoes give a mutual penetration without a bulky harness. The bulb fits, just right, into the anus or vagina and can stay put while the partner is being penetrated. The biggest change for the Stout, versus the other models, is the width (it's wider). Now you can experience fullness like never before. The shaft is 1.75" in wide and 5.75" in length, while the bulb is 1.5" wide and 3.5" long. All Feeldoes are made out of 100% medical grade silicone.
