AFTER Martha Stewart joined Match.com in a desperate bid to jump-start her comatose love life, critics are blasting her for promoting pro­miscuity among seniors!

The 71-year-old do­mestic diva recently posted her profile on the Internet dating site, and later told Matt Lauer on the “Today” show that she’s looking for a man to “go to bed with and wake up in the morning to.”

While that may seem like an innocent wish to some, rela­tionship experts say she’s sending out a very bad message to elderly daters.

“It’s very irresponsible of her to suggest that she is looking for a sleeping partner and not a long-lasting relationship,” said Dr. Jack Singer, a clinical psychologist and sex therapist from Orange County, Calif.

“She should have emphasized that she wants to develop a rela­tionship with someone of substance and then, down the line, have a romantic or sexual re­lationship with him.”

DR. Singer points out that many online daters lie about their personal and sexual histories, and that sexually transmitted diseases are on the rise.

In fact, the rate of STDs – including chla­mydia, gonorrhea, syphilis and HIV – has doubled in the 50-90 age group over the past decade.

The domestic diva, who is currently promoting her new book, “Living the Good Long Life,” has been single since her split with software magnate Charles Simonyi more than five years ago.

Since then, a source said: “Friends and family have tried to set Martha up on blind dates, but she hasn’t found a love connection. So now Martha is going to literally hold auditions to find a man.”

On Martha’s dating profile, she describes herself as “athletic and toned” and says she’s seeking men between the ages of 55-70 in the New York City area. Social drinking is OK, but smoking is a deal-breaker. And her dream guy needs to bring in more than $150,000 a year.

Dr. Judy Kuriansky, a noted New York-based clinical psycholo­gist and author of “The Complete Idiot’s Guide to Dating,” believes Martha’s foray into online dat­ing is nothing but a calculated publicity stunt.

“Her businesses are strug­gling and she wanted to say something sensational that would get people’s attention and help promote her new book,” said Dr. Kuriansky.

“BUT I have been warning people for the past decade about the dangers of sexually transmitted diseases among seniors, and she should not have been so flip about saying that what she wants in a man is someone to go to bed with.

“This statement would be as­sociated with having sex with the person, which makes the remark irresponsible and promotes pro­miscuity.”
