How can I be more comfortable with this dance move?

Question:

How can I be more comfortable with this dance move?

I take ballroom dance lessons and I am rather good at it. I have been dancing for about 3 years now and I really love it. I have long legs, a skinny frame, so I am made for it.

Anyway, recently I have started a group formation class. For those who don't know what that is, it is when a group of people do the same steps while wearing the same clothes (usually black, plain, makes everything look really cool).

Anyway, at my last lesson, my dancemates were sick or on vacation, so I was the only one there. Me and my instructer got pretty far, and at one point I needed to do this step where I stick my but out and rotates it in a circle.

I am honestly not comfortable with this step. I have a competition coming up for this formation group and so all the girls will be doing this step, but I am embarressed about it.

How can I not be embarressed? I felt so strange while my mom watched (she always does) and my instructor showed me how far to stick it out.

And I don't want to ask my instructor to change it, because I know this might happen with a different step so I really need to know how to relax about it and not freak out.
