I'm sure she wills till like you (personally i think its a bit shallow to not like someone because french kissing them for the first time was awkward, especially when it was her first time too!) so I'm sure that's not the case. I think you just need to wait a short while to try it again but maybe just 'normally kiss' if that makes sense! because the longer you leave it the more awkward it will be whee you do it again! just let it happen spontaneously. when your just kissing, try just turning it into a french kiss, go slowly and see how she reacts

good luck
