bloody sex

since i got my rod about a month ago, every time me and my boyfriend go to have sex - even a little touching (fingering), can make me bleed a little and it’s not like he is continuously cutting me because he doesn’t have long nails. it makes me really uncomfortable and i can’t enjoy sex as much cause i’m constantly worried about getting it on his sheets and stuff. has this happened to anyone else whilst being on the rod? did it stop? i’m so sad, this was meant to be good for my sex life but it’s not helping much /:
