Buck-Off Angel Stroker the World’s First Transman Sex Toy By Buck Angel and Perfect Fit Brand. The Buck-Off – the Official Buck Angel Stroker – is a toy designed for transmen to explore their bodies. What makes it unique and specially designed for the transman? We developed the Buck-Off™ for t-cock/enlarged clitoris which is a common physical change during transition while on HRT. The Buck-Off™ is a product that provides a different option for masturbation from the traditional vibe solution. It was carefully designed with micro-ribbing internal feature that will stimulate average to larger clitorises. The opening on the Buck-Off is right-sized!
