His wife made him wait till the son left the house before sexy time. I would have done anything to get my kids to move out sooner if that was the case. I helped make you, fed you for years and bought you stuff, time to get my wife back. Once the kids are iold enough you just have to wait for them to have a sleepover at someone else's house. I would have let him know it was safe to come back around 8 or 9 months. Once the baby is born everyone is too tired for sex. Then there are the months where any time you get to sleep through the night is a holiday.
