Bleeding a lot from sex on the rod !! HELP

Amber

So I was having sex with this guy, and it was good until it started feeling a little painful and ‘different’ so I get up from riding and blood pours all over his dick and stomach and I got all dizzy, it lightened up soon after but bled lightly for a few days.

It’s the first time I’ve had sex since getting the rod in about a month ago, idk if that’s why but I wanna know before I try again with him 😅

What are your experiences what do you think ???
