I think I'm broken

The past few nights my man and I were trying new things usually pertaining to anal and things like that. while he does me vaginally from behind he would start fingering my ass or when he was eating me out he'd eat my ass too. So last night he was fingering my ass while doing me vaginally from behind and he pulled his finger out and was really going at it super fast and he accidentally pulled out and on re entry he also accidentally put it in my ass immediately I yelled ow and he went from hard to soft in .01 seconds and he held me for a bit. I guess bc he went so hard and fast it hurt and I'm pretty sure I tore. How long is this pain gonna last??¿¿
