I would just order the fruit like it's no big deal, if he says anything about
it just be like "oh I have some stomach troubles, so I like to watch what I eat". Although I told my boyfriend every little detail about
my Crohns before we even met!! we met online, I don't suggest throwing yourself out there like that, especially on a first date. If things progress and a second date is set, then I would go on and mention Crohns. You're Crohns does not describe you, but at the same time you don't want to lead him blind.
