Q. Do you exercise regularly?

No, but I did see something brand-new I like. I take a lot of taxis. In New York, the taxis now have a woman on a video screen who teaches exercises while you ride. She tells you to pick up your pocketbook with one arm, then the other one and count to 10. Sit straight. Pull in your stomach and count to 10. I love it. That means you are using your time productively.

Q. Let’s talk about your advice. What is the biggest concern you hear from people about sex as they age?

The biggest concern — and correctly so — is having an erection for men. That is one of the reasons I came out with the wine, Dr. Ruth’s Vin D’Amour, a line of low-alcohol wines from California. It has only 6 percent alcohol. Drink a little because everybody has stress; don’t drink too much. She falls asleep and he can’t have an erection. That is particularly so for older people.

I tell older people, “Don’t expect the same intensity of your sexual response. Engage in sex in the morning, when the testosterone level is highest and after a good night sleep for her. Have a little breakfast, hang the phone off the hook, go back into bed.”

Q. What about for your own self as a widow?

No personal questions! But I will tell you one funny thing. I was just in Washington. I got the Margaret Sanger award. I was kissed by President Obama. I haven’t washed my face since. So I tell the story about my late husband, Fred. He loved Diane Sawyer. One time, 60 Minutes came to my apartment. I didn’t have the heart to say to Fred, “You can’t be home.” So we are sitting down and Diane Sawyer, the first question, she said, “Mr. Westheimer, how is your sex life?” To which he answered — and I have it on tape — “The shoemaker’s children don’t have shoes.”

So I tell everybody, in the Talmud, the Jewish tradition, it says a lesson taught with humor is a lesson retained.

Q. Has your audience changed as you’ve gotten older?

The questions have not changed. There is a lot of loneliness. There is a lot of people divorced or separated or who have never found a partner.

Q. Is romance dead?

I think we have to talk more. I don’t think it is no romance, but not enough. I’ll tell you what else worries me. I see young people holding hands and with the other hand they’re texting. People are going to lose, and not just young people, older ones are going to lose the ability to converse, the ability of conversation. They are being fed the news all the time. They lose the ability to concentrate.

Q. What’s wrong with that?

It will have an effect on the relationship. I do believe a good relationship — I am not against people having a phone; I have an iPhone — but I want people to not lose the ability of interpersonal relationships. When I want to be with someone, I want to touch them. I don’t want them to be on the Internet.

Q. What do you hope your legacy will be?

I think people will say she had the guts — in Jewish tradition, it’s called chutzpah. She had the nerve to talk about things other people were too worried to talk about. And she hopefully helped prevent unintended pregnancies and she helped some people to have a better sex life, until the late stage in life. Even have orgasms.

I don’t mind if people say they get aroused by my radio program; I think that is great, I provided you with foreplay. But take it seriously. Don’t let boredom creep into your bedroom.
