High expectations

So basically I have a big sex drive my boyfriend does not. So we can go a month without sex and then I still have to initiate it (super frustrating and almost humiliating like really do you not think I'm sexy) anyway I spend the time we don't have sex thinking about it and building it up even when I don't mean to so when we have it not only is it quick but underwhelming because of how much better I imagined it. Does this happen to anyone else or am I like a over excited freak 😒😢😰
