I hate to bruise the male ego but will have to agree with OT and Lil on this one for sure. There is no way I guy can tell if his partner has O'd. I know that will drive BF crazy but you might as well here the truth, right? It's not a reflection on how the man is as a lover. It is ultimately up to the W to make herself reach an O. So what's the big deal? Why do guys take such offense? Whatcha think BF?
