labia swelling

The strangest thing happened today. After sex, I had the weirdest feeling between my legs. I had my husband look down there and my labia minora were swollen to like 3x their regular size. It wasn't the most comfortable thing, but went away after a couple hours. I've never had this happen before.

couple questions for ya:

1) Has this ever happened to any of you?

2) He kinda liked the way they looked and felt.. is there any way to re-create that on purpose?
