I think the policy of "the more serious the interest the more open the disclosure" is a good one. The only "untoward" thing that can happen with such a policy is is meeting a gal like me who would feel challenged by the impediment. It could be simply out of a desire to overcome unusual challenges (the reasoning would go along the lines of "it is no big deal to attract a regular guy - they flock to me en masse anyway - but this one... this one... this one poses a challenge I want to to conquer" or along the lines of "oh poor creature! It is as if an evil sorcerer had put him under a spell. I must try my best to free this man from the wicked black magic. Oh poor thing... and so delightfully attractive at that".

So beware of those who are up to special challenges
