That's bullshit. I'm 41 and I've been married 14 years, we have three kids (the youngest is only 7 mos. . .surprise) and we're still banging away like a screen door in a hurricane. . .3, 4, sometimes 5 times a week. I suppose it could "all go away" if you let it but, I just can't keep my hands off of her. She reminds me once in a while about our pre-marital days, when she would get to feeling guilty about having sex all the time and she would shut me down once in a while and I would tell her. . ."When I'm 40 years old I'm not going to be like this anymore and you'll be sorry." She wants to know when I'm going to run out of gas like I said I would. We laugh about that one quite a bit. . .
