Not going to have anymore kids? Get a vasectomy. I did.
Not that big of a deal really.
Takes the worry out of what goes where!
Then, you'll probably discover that you want to and can come inside all the time, as there are no worries.
After a while, you'll decide that maybe outside would be fun now & then too.....you, and hopefully both of you, miss the show & the mess.
Ask me how I know that!
