Not being able to orgasm for two nights is normal and nothing to worry about. It's common for people to orgasm different amounts and in different ways. And sometimes how often, how easily, or through what kind of stimulation a person orgasms can even change drastically from one point in their life to the next!

and that's where "faking" comes in when you're just tired of doing it, lol.
Faking is not recommended. Faking is lying to your partner. Faking can give your partner the wrong idea about what works for you and what doesn't. And faking can give your partner the impression that girls orgasm every time. If your partner is ever with an honest girl in the future who doesn't happen to orgasm every time, that can leave him feeling very confused. It's better and healthier to be honest and help your partner to learn about you, your body, and that fact that it's ok for someone to not orgasm.
