Why do you consider it embarrassment? Sure, people will notice, and some might get annoyed or something, but biggest impression that people will end up having is your attitude. Try not to give a shit. If you are meeting someone for just that one time, who cares what he is going to think? You won't see him anymore. If it's someone you might keep seeing, he will either have to accept you for who you are move along his way. Either way, it won't be embarrassing. I mean, when people without arms or without legs, who have it much worse can go out there and do sports or whatever and enjoy in life, you can do it too. Don't let your stutter to bring you down, it's part of you, it's who you are. Embrace yourself and love yourself.
