<human>: This happened a year ago, but I was just reminded of it and think it's worthy.

Last February 14th, Valentine's Day, my fiance had planned a perfect day. We went to Red Lobster, he bought me lilies (my favorite flower) and was pretty wonderful the whole day. 

On the way home I offered him anal (which we hadn't tried yet) because it was such a great day, he accepted, but we had to stop and buy lube.

We stopped get home. Not even five minutes in the door and we're in the bedroom. He lubes up and instead of anal. I get on top, after a good while on top, he grabs my butt, holds it, and takes control from the bottom. 

Only problem, we were pretty slippery... Next thing I know I am in serious pain and crying and he is telling me he's sorry.

He had slid out and literally rammed himself into my ass. I bled and walked awkwardly for a few or more days. Also had to go to the doctor, where they gave me medicine to help with the pain.

Could you distill the essence of the text into 1-3 sentences?
<bot>: Had Valentine's Day sex with fiance, wanted to try anal. Instead we do cowgirl and he ends up making me cry and also make me bleed from my ass.
