From Milli Hill's excellent The Word is Woman newsletter, this is a sexual pain study being run from Oxford University. It sounds useful and sensible apart from the fact it dare not name that class of "people" or "individuals" who have had "a vagina from birth".
What a gross phrase, as well as just sounding mad. Did you have one from birth or did you pop one into your shopping basket when you were buying milk one day?
Surely they can't be using this mad newspeak to differentiate women from the results of certain surgeries that some trans-identified men get?
