I've never been married, but I had a male housemate for 7 years, so I know something about living with a guy. If I may offer a few simple rules for the gentlemen.

Your private parts will not fall off if you do something a woman asks you to do.

You won't turn into a woman if you pick up something that falls on the floor.

You won't turn into Phil Donahue if you wash a dish, launder a sock, or flush a toilet.

Don't expect your lady to look like J-Lo, unless you're willing to look like Ben Affleck.

Washing, brushing your teeth, wearing clean clothes, shaving off stubble, will not turn you into a sissy.

Those athletes you spend every Sunday watching don't know you. They didn't run all over town to buy you that grownup toy you wanted. They didn't look after you when you got the flu. They don't sit through assinine movies because you like them, or put up with godawful music because you love it. They also don't have sex with you.

Just as a PS. I paid a visit to one of those internet dating services, on the advice of my sister. (Dad used to call her idiot child the second. The dog was idiot child the first.) I found a surprising number of single men past 40, all of them avid sports fans. I think they spent so much time watching the game, that they haven't had a chance at a relationship. I can't think of anything women do that's like that. (Most soap opera junkies have 1 or 2 soaps they watch regularly. You can miss 3 or 4 episodes of a soap, and miss nothing in the plot.)
