I always find it really funny how authors just think its somewhat normal to bleed during anal sex. Unless you are being r*ped or *insanely* underprepped (like broomhandle dick meets hole the diameter of a hair), this is not an issue. Men don't have hymens in their ass.
If someone did bleed from anal, especially as much as we see on those sheets, I'd be scandalized from the non-reaction by the top. That's a doctor's visit in the waiting lmao.
