Please read...anal newbie

My husband and I are newer to anal, bit we've used his fingers and his 'member' before... The other night he used his pinky so he could be in more than one place at once.... It was great.

Except afterwards he said he had blood on his hands. I got in the shower and it was bright red blood coming from my behind.

The next two days anytime I would go to the bathroom there was a little bit of blood. Today when I went #2 there was fresh blood again.

Ive read this is normal How long does this last?
