It’s so good & so bad

Some girls have all the fun.

Kim Ramsey, a nurse from New Jersey, has hundreds of orgasms a day — in cars, doing laundry, buying food in a supermarket.

But when the skyrockets start to go off, she doesn’t cry out, “Yes!’’

Her reaction is, “Oh, no, not again.’’

Because as far as she’s concerned, you really can have too much of a good thing.

“Other women wonder how to have an orgasm,” the Montclair woman told London’s Sun newspaper. “I wonder how to stop mine.”

She’s probably the only NJ Transit rider who ever credited the commuter line with bringing her to climax.

She recalled a recent train ride home that she said left her shaking.

“It was a bit of a bumpy ride,’’ said Ramsey, who moved to the United States from England.

“Every jerk of the train or vibration made me more aroused.”

“It was a 40-minute journey, so there was nothing I could do. I just had to bite my lip and sit on my hands and hope no one noticed.”

Her problem began four years ago, after she had sex with a new boyfriend.

“I had constant orgasms for four days. I thought I was going mad,” she recalled.

“We tried everything to make it stop. Squats, deep breathing.

“It also happened with a new partner. I even sat on frozen peas, but the orgasms and sexual arousal continued.

“I must have had around 200 orgasms during that period.’’

But it was no romp in the hay.

“The pain and exhaustion, Ramsey said, was “unbearable.’’

She said she contracted a recently identified and very rare medical condition, persistent genital arousal disorder, which makes any pelvic movement trigger an orgasm.

“Imagine feeling aroused for no reason other than you got up that day,’’ she said.

Doctors believe that Ramsey may have come down with the condition when she developed spinal cysts after falling down a flight of stairs in 2001, but it remained dormant until her marathon sex session with her new boyfriend seven years later.

The incurable condition, she said, has made her life a nightmare.

It’s not clear if she has a boyfriend now — clearly no guy can keep up with her — and she said that the unending climaxes make her feel as if she’s unable to have a normal relationship.
