Overly wet during anal who else?

I’m on my period and me and my boyfriend decided to have sex thru anal I had a tampon on and he fudged me in the butt and came inside my ass when i got up my vagina was soaking wet like my tampon was soaked in cum of my own literally drenched all over my thighs and the string just full of cum I literally wet my whole bed with how wet I got from my vagina even tho he fucked my ass, anyone else experienced this it’s like my period stopped to let me cum all over him. I must have a g spot in my but cause I was drenched
