This thing has been great....not just for the masturbation but... I'm dating this hawt girl. 34d, ass to die for and all around really good. Stamina was never a problem for me but this girl can get my rocks off like no other. Not only am I making it through her orgasm now but she is having two before I am ready to pop off. Funny though...at times she is orgasming before I get in. I guess we're doing very well in the sex dept but the fleshlight has helped! I have the stu but am thinking about getting one of the orginial smooth interior kinds for variety!
