We wiped it off ,and when we were done, my private zone smelled like his

So me and my boyfriend had anal sex and his penis was wet and my vagina was wet also. Sounds nasty,I know. 

Well his penis touched my vagina and it was wet. We wiped it off ,and when we were done, my vagina smelled like his penis.

I know his penis was in my butt. But I'm worried,could I get pregnant? HELP
