Associating love with sex

Does anyone else feel not fully loved by their partner unless they’re frequently having sex? My husband and I are in our early twenties and have been together a little over a year. I truthfully could not ask for a better partner but if sex is not happening every single night, it affects me so deeply and so negatively. I can’t shake the feeling that I’m and unwanted and unloved for the whole next day if we don’t have sex the prior night. I’m so blown away by all the posts I see related to women not wanting to sleep with their man bc I literally feel like I have to have it to feel complete for the day. Are my feelings even somewhat normal? How come sex is so important to me but not to all these other females?
