How to get over shyness by this project?!?!?

Well, Im not a really shy person but im doing this project on "Can you tell a persons gender by looking at their feet". (iknowiknow gross). So i took pictures of 7 feet. One picture... The feet is from a 60 year old neighboor and its reallly grooooosss. And now im scared to present people are gonna make fun and say "ewww" during the presentation. How do i overcome this embarment if it happens and my shyness?
