If he is willing to shove your face against the floor and hurt you while you do not want that, it's time to reconsider the reason you're dating this person, and how they will treat you for the rest of your life (unless this person is a one-night stand type deal. Still, time to adjust your judgement).

Why didnt you tell him to stop?

I understand losing your V but your step-sister rm, why In hell wouldn't you go to your rm lol

it seems to me that having sex in one's siblings room and not one's own room has become very popular. *ashamed of human race sigh*

I'm sorry sweetie, that's not how it's supposed to be. The only consolation I can offer is that years down the road, you will laugh about it with your friends and that sex will get better. And please choose men who care more about your wellbeing.

Should have at least grabbed a pillow. Also an odd spot to do it for the first time. Hope the step sister didn't find out after the fact.

If youre old enough to have sex you should be old enough to tell him if its uncomfortable. YDI

I dont understand why they can never do it in their own room on their bed. Why did you choose the floor of your step sisters room. Honestly...
