If you want to increase your sexual desire then try using the fantastic Ben-Wa metal balls. They're small, weighted balls designed to be inserted in the vagina.
You can use them either as a sex toy and masturbatory aid or as a training device used to strenghten the pelvic floor muscles.
Pelvic Floor Training:
During sex, a woman's ability to contract her muscles around her partner intensifies the sensations for both of them. Training these muscles can help you prevent potentially urine leaks when the muscles weaken due to aging, childbirth or obesity. That is why the Ben-Wa Balls are perfect to help you focus the exercises that help you strenght the pelvic floor muscles. Just insert them, hold them in place for several minutes as you move around naturally and then release. You can also perform kegel exercises around them.
Sex Toy:
They can be used on their own or with other sex toys, like a vibrator. Is not about inserting them in and out, but about the feeling they give you when they vibrate with each movement and spread a pleasant vibrating feeling in the abdomen. They heighten awareness and arousal when they're left inside or they're moved gently. Women love this kind of stimulation.
Please note : do not insert in the anus, do not use for longer than four hours, do not use during or shortly after pregnancy.
