Pap smear, menstrual cup and sex are completely different experiences. Someone can desire and enjoy penetrative sex while finding a speculum, tampon or menstrual cup painful or uncomfortable because of involuntary pelvic floor tightening. Factor in things like arousal, lubrication, context, anatomy and consent. Being comfortable with one specific type of penetration doesn’t mean you’re comfortable with every form of penetration. Relax with the condescending tweets please.
