You didn't spoil anything.

I guess strange things happen all the time. I've heard of some very interesting objects becoming stuck where they had no business being. I know her IUD has a string but I didn't think it had enough of something for a stud to get caught on it and pull the iud out. I guess I don't understand why he stayed erect after all that.

I can't imagine being the bottom one when someone decides to "die in the saddle". Dead weight takes on a serious new meaning then.
