Cup nerves!?!?

Well here I am again!

Three years ago I bought my mooncup (didn't realise it was so long ago ahh) and had no success... I said I'd try again when I was older and no longer a virgin...

So here we are, and I've just tried inserting the cup again and I couldn't because it made me so nervous!! Aggh! Why can't I get over this??

Any tips?
