Bustersday:
Why are you afraid to go on outings and to Church?  Is it due to the fear of having a visible leak or maybe the stigma attached to someone finding out you wear protection?  Although I haven't had a prostatectomy (yet, but probably will in the future) I have been bladder incontinent to a lesser and now greater extent for 7 years and wear diapers 24/7. I can say that with a bit of preplanning, and wearing the appropriate protection, it hasn't stopped me from doing anything.  I will admit that swimming is a challenge but I even have a strategy for that.
I can easily get by on 2-3 quality diapers a day and even 1-2 by strategically adding a few pads.  I have to say I am constantly surprised at so many of the posts here, especially from guys that have had a prostatectomy, that seem to prefer a huge number of pads or pull-ups (with all of their limitations) over just a few quality diapers.  I do understand that becoming incontinent is a huge shock, and can be difficult to come to terms with, but with such great products available it doesn't have to be life changing.
Finally I have to say you made a great choice in coming to this forum  to find some help.  We are all very understanding and will try to help you in any way we can.
