NEW YORK Sunday night is getting less steamy.

Oxygen's "Talk Sex" call-in show with colorful septuagenarian educator Sue Johanson is ending its run after six seasons, the network announced Tuesday.

The final show will air Sunday at midnight.

"I'm going to miss it terribly," Johanson said. "It's been part of my life, and I just love it. I'm going to miss writing scripts. I'm going to miss having to read books. I'm going to miss playing with sex toys."

Her final show will count down the year's Top 10 sex toys.

The show, derived from a Canadian radio program that began in 1984, offered practical advice and the latest information on sexually transmitted diseases. It was all the more colorful hearing it from a Toronto-based nurse who looked and sounded like a grandmother.

Now 77, Johanson said she had to recognize that 1 a.m. (when her shows ended) was not her finest hour. Because it's a call-in show, taping the show earlier didn't make sense.

"I have been on television for 32 years," she said. "I think it's time. I figured if we haven't got it by now, we're not going to get it. We've got to make room for somebody else."

Johanson said she enjoyed working with Oxygen and wasn't pushed out. She said she isn't retiring and will continue to give lectures.
