I have a new partner and there is no blood during or after sex. However during forplay when I lay down with the fingers I tend to bleed. He tents to get a little high. It doesn't hurt while doing it but a little after for a few hours. Though when he does the same when I am standing there is nothing. What can it be?

I'm not quite understanding. Do you mean when you are lying down and he has his fingers in your vagina, he tends to go far inside and you bleed then?
