Orgasms are harder for women to reach after menopause due to reduced pelvic blood flow and less sensitivity. Vibrators increase blood flow to the pelvis and provide the prolonged stimulation many senior women need for arousal and orgasm. Many older women also require more intense stimulation due to less sensitivity, which vibrators can deliver. They can be used solo or with a partner.
You'll find three basic types of vibrators here:
Clitoral vibrators are small (usually palm-sized) and are used externally to stimulate the clitoris and surrounding areas. One type is called a "bullet" - these vibrators are designed for intense pinpoint stimulation.
Dildos and g-spot vibrators are penetrating toys that are used for internal stimulation. Many have rotating as well as vibrating motion. Some have external features (like "rabbit ears") to stimulate the clitoris at the same time.
Massagers usually look like a wand with a vibrating bulb-like end. They tend to provide very strong vibration and stimulation. Many, like the famous Magic Wand, can be used for other areas of the body as well as intimate massage.
New to vibrators and not sure where to start? Try a small clitoral vibrator—most women are more likely to orgasm from clitoral stimulation than vaginal. Penetrating toys can come later.
