I've never disclosed my past medical history to anyone upon meeting them (I only see it as a correctable mishap) and most people I meet do not disclose their medical conditions either, unless there is a need to do so. My advice is to just be yourself and if you find yourself leaning into what may be a romantic or physical relationship -- then you will have to cross that subject matter. By then, he will have come to know you as the wonderful lady you are (with a fantastic aptitude for math no less) and not come into the possibility of a relationship with a 'preconceived' notion. My two cents worth and if you rub the two pennies together they wont start a fire ;-)
