Yes I love cheer. I was the same, the only other sport I did was swim. Once. I tried & I made it. You should try, everyone gets better with practice. It is really fun and a boost to your self confidence. Go for it girl !
Cheerleading is like gymnastics and dancing mixed- to do cheerleading you need to be fit and flexible. You can't be scared of the tumbles or the lifts so if you get scared easily I wouldn't suggest it but I suppose you could give it a go
