1. Give yourself time. As you age, your sexual responses slow down. You and your partner can improve your chances of success by finding a quiet, comfortable, interruption-free setting for sex. Also, understand that the physical changes in your body mean that you'll need more time to get aroused and reach orgasm. When you think about it, spending more time having sex isn't a bad thing; working these physical necessities into your lovemaking routine can open up doors to a new kind of sexual experience.
