Woman ejaculation

So recently my boyfriend and I have started having sex and I have never came as much in my entire life. Seven times in one session Crazy! Anyways I think my body chemistry has changed since then. I masterbate often and I started to notice when I cum the consistency is different. It’s now more creamier and the color is different. It used to only be clear. Not it’s bright white. Could this be from him or my birth control. Which I’ve used for years (NuvaRing). Please help a girl out!! Thanks huns 😘😘😘
