Marriage doesn't mean the death of hot sex, it takes some effort from both of you to keep it steamy as the years go by.
1. Try to stop thinking of her as your adorable and adoring wife when the two of you get frisky, allow your imagination to run wild. (vice versa)
2. Don't wear pajamas-continue to wear your sexy lingerie.
3. Make a date night with your spouse and meet at your local bar.
4. Stop saying you have no time or you're tired, make the time.
5. Use sex to get past your ruts, it'll help you reconnect.
6. Just do it, don't plan it.
