The Dong with Balls, it feels pretty realistic, and for me, I am a single bi guy, for those nights where I just want some anal penetration, this does the job... It feels good, it stings a little if your into anal stretching, and it just relieves and unwinds after a day of tension.
I would reccomend this if someones looking for an actual dong, rather than just a dildo. It feels quite realistic as far as penetration goes. Though it IS a bit tough to get in at first.
