This isn’t true. I have orgasms from the uterus. It can happen while being penetrated, and it can also happen handsfree to me, when I’m reading fanfiction, watching amateur porn, or listening to my partner talk dirty over the phone. It feels like my womb is clenching of its own accord, and creating pulsing waves of pleasure throughout my lower belly. Not connected to the clitoris at all. And I should know, since I’ve had thousands of clitoral orgasms throughout my life.
