Can u "over do it" with sex? is there a non surgical answer besides a pessary for prolapsed uterus?

Not really. Yes.: You can't really "over do it" with sex. Their are other options for prolapse in some cases. If the prolapse is mild then you could try pelvic muscle rehab with biofeedback and electrical stimulation. If your prolapse is more advanced then surgery or pessary are your best options. You could choose to do nothing depending on severity of symptoms.
