Dumb question but idk

Ok so a couple of days ago, my boyfriend was fingering my ass and I've never found my g spot until then. Like I felt I needed to pee but it was also super good too like I was gonna cum any moment. My question is, can women have their g spot located in their anus instead of the vagina? Like I thought that was only for guys. I know sounds like a dumb question but I'm honestly curious
