If it were me ....I would not be worried about discussing BP or his possible ED ... Why not take the stress off and just have a conversation, just talk with no conversation check list to adhere to. You and him have known each other for a long time, I am certain you guys could "catch up" for days.

I have gotten in touch with a lot of people from my past, I have plenty of things to talk about, catching up to do .. I am not ashamed of my bipolar but I feel no need to tell everyone about it. I seldom even talk about having cancer and being in remission.

As far as taking your meds if it makes YOU feel better to go to the bathroom to take meds then by all means do so. I have taken my meds in front of all sorts of people and situations and never feel the need to explain what they are for or why I need them. People all over the world are taking meds for something or another and do it in public.

My advice is don't over think everything and just go and enjoy yourself.
