Sexual weakness most frequently is that of perineal muscles. This is known as the pelvic floor. This muscle group is very powerful indeed a floor on which rest all the organs in our belly, starting from the gastrointestinal tract and female sexual organs like the uterus, fallopian tubes or ovaries.
But this floor is often too weak, insufficiently muscled.
This is why Dr. Kegel, an American gynecologist, invented in the 1940s, a series of exercises for this muscle area.
Who can benefit from the strengthening exercises? Almost everyone!

Indeed, a few pelvic floor muscle has a tendency in humans to cause too fast ejaculation and decrease feelings of sexual pleasure. In the perineal muscles, it will better controlling ejaculation.

In women, a few pelvic floor muscle is the cause of impossibility to achieve orgasm, a experienced low sexual pleasure.
In a woman who has just given birth, the problem may be important because birth has stretched the muscle fibers, thus, have a real need of rehabilitation to regain their tone quickly. This is why most gynecologists now prescribed in the puerperium, sessions Perineal rehabilitation from a physiotherapist.
It is however unfortunate that we often explain to the women concerned only one aspect of this weight: its interest in preventing urinary incontinence. This effect is certain, but the effect on sexuality seems equally interesting in young women whose sex life is a priori active!

Finally, the weight is not useful sexual aesthetically speaking like most exercises, body building, but it is useful for sexual function and pleasure, which is just as interesting!
