" A spouse's first choice for sexual gratification should always be the partner "

You're planning on sleeping with your partner multiple times a day? For 40 years? Every time you use the word "should" .. beware, because you're judging someone else by your own standard.

Some people simply have different internal clocks. A woman who only wants sex twice a week can, in fact, discover that she's dating a guy who wants it every day. They're not wrong - they just need to understand each other's clocks, and work out an agreement.

And no, "He stops!" isn't an agreement.. that's a guaranteed breakup.
