The million-dollar question

During our week home sick together, my son did a lot of whining and a lot of snuggling. But he also came up with plenty of interesting things to say, including this question he asked of me while I was peeing:

"When are you going to get a penis?"

My response about that he would, sadly, not be growing a uterus any sooner than I would be growing a penis did not, I'm afraid, appear to satisfy.
