So as the title post suggests, I've been having some performance issues as of late (about 6 weeks) of prematurely finishing when when engaging in sex with my plate.

It's very strange, almost as soon as penetration occurs I can feel me inching closer to climax by the second. And let me state as well that I don't have this issue with other girls.

DAE have any experience or tips/techniques to boost my stamina?

Thanks
