Dealing with doubters....

So a week and a half to go... Mentioned my appointment to a few close friends/fwbs... Got some negative feedback such as you're going to ruin your dick, no one will want to blow you etc, take your mid life crisis out some in other way .... Please tell me they are wrong!? I am super excited but no one seems to share my enthusiasm... I would sure appreciate some positive vibes from you guys....
