What changed ?

Hey guys ! So my boyfriend and I have been together for almost 2 years ! When we began dating , that’s when I became sexually active. So yes I’ve lost my virginity to him and during that moment , I use to cream a lot while doing it. So overtime , i noticed that I don’t cream as much. I don’t cream at all anymore now. & yes , I be wet & no , we don’t have sex every day. But I’m just confused on why I don’t cream anymore. Any tips on how to again ?
