Orgasms achieved through cervical stimulation follow an anatomically different neural pathway than clitoral or G-spot orgasms—the cervix is connected to the vagus nerve, which is directly connected to the brain, bypassing the clitoral/vaginal nerves.
Why the sensation is different: Because of this different neural pathway, many women describe cervical orgasm as more “spread out,” wavy, and less localized than clitoral orgasm.
Necessary prerequisites The cervix is deep and can be painfully sensitive until sufficiently aroused — without sufficient foreplay and arousal, intercourse often becomes uncomfortable.
Who it's not for Some women don't like cervical stimulation at all or find it painful at any level of arousal—this is a perfectly normal anatomical variation.
