Faking it

I have to ask. How many of you fake an orgasm? Personally I don't. I feel like if I do fake it he will think he did his job and he will stop trying to actually give me one. Because I know he holds off until I Ummmm you know. So if I fake it he thinks he's done his job. He definitely makes sure I've had mine before him. Now I'm not saying I have one every time but almost, I'd say 9 out of 10 times. I'm such a lucky girl lol, but even if I don't I don't fake one. I don't think I have to do it in order to make him feel better about the sex we have. We both know that it's great sex even if sometimes I don't have an orgasm. I was just wondering how many women actually fake it.
