What is ‘cream’

Me and my boyfriend had sex today and we recorded a video but he said I came because there was white stuff on his dick when he was fucking me. However I didn’t feel like I came so I assumed it’s ‘cream.’ When someone says , she has a creamy pussy (gross but only example I know of) what do they mean? What exactly is cream?

I’m on the depo shot (bc) so i dont ovulate anymore if that helps
