There are lots of causes of libido loss or crummy orgasms.
But, in the absence of any physical, neurological, mental health, contraceptive or medical ishoos - might well be connected to the pelvic floor.
The nerves that supply your tickly bits also supply the muscles of your undercarriage. At orgasm, there's a muscular contraction. There's lots of evidence that shows having strong muscles = stronger, longer contraction. Cos, who can be bothered in return for a flap? If you're going to Do It you may as well make it worth your while.
The pelvic toner is a gadget that has a spring, so it works on resistance. It has good evidence backing it up, and you can have it prescribed by your GP in some PCT's.
You are right though, you don't NEED one. You NEED to doyerblardyexercises - and the trouble with that is they are boring and easy to forget. I'm tweeting x3/day as a training reminder - when I tweet, you twitch your twinkle. Stick an @onto my name, don't want to fall foul of advertising laws by putting in a link...
Crummy sex life and continece ishoos (front and back) are common. Really common. 1:3 officially - but Lorraine from aff ra telly found it was 75% wh'd admit it to her.
You don't have to put up with it. I'm quite keen for MN to run a campaign - most women don't know what to do, but do know they should be doing soemthing.
Fancy it?
