There is absolutely no quality research on this. There is no evidence, so this statement is misleading. Self-reports published in psych journals really don’t count. Nerve testing needs to be done to evaluate effects.
Compare whatever bs “research” they’ve done on this to studies of how power tools affect nerves in people’s hands. It’s night and day. With women’s genitals, there’s always a bunch of bs. It’s all about feelings and not science.
