Okay, you’re having sex and you’re about to have an orgasm, and you (very considerately) want to let your partner know, so that he can either join you in the experience or ask you to wait if he needs a little time to catch up (or, if you’re beyond restraint, make sure you don’t stain his sheets). So you say, “I’m coming!”
Why do you sound so surprised?
What, you weren’t expecting this?
What is it about the experience of orgasm that makes us tell each other about it not only as if we had never done it before and were shocked and thrilled to find ourselves capable of it, but as if in fact no one had ever done it before and we were shocked and thrilled to find anyone capable of it, much less ourselves, and secretly proud that we were the first?
Do girls do this too?
