It's part of who you are. Either he accepts you for who you are, or he doesn't. What you do after that will be clear.
Did he announce his visit, or ask? I found that part of your post somewhat disturbing. Especially given you have a teenage daughter who he has never met before. 'Several weeks' is a long time. Personally, I would never subject my child to this kind of visit for this length. I would suggest he stay elsewhere and you introduce contact gradually.

Second thoughts can generally be amended with judicious action; injudicious actions can seldom be recovered with second thoughts.
