i think there’s something wrong

i’m 16 yo and i was hooking up with this guy and he started finger me. I had him use 1,2 and 3 fingers but i didn’t feel anything and i had to fake my moans. He went at it for ab an hour and a half and i didn’t know what to do. he was moving like his whole hand in more of a stabbing motion than his fingers. I was also on the last day of period but there was hardly enough blood for a light tampon and my cherry was popped a few years ago. Why didn’t i feel it when he fingered me
