I have tears in my eyes laughing at that.........
Me, too.
For any man who thinks that you have more sex after marriage, I have two words of advice (especially true today):
Stay single!
There is so much energy expended in raising kids (and I wouldn't change anything), that by the time the kids are in bed, there's nothing left in the tank.
BTW, it's even worse after they become teenagers! Even with a reasonable curfew, you worry yourself silly over them being out at nights. Plus, I'm having to teach myself Geometry (among other subjects) again, so I can check his work.
