The last guy I dated told me I kiss too fast should I tell the current guy I am dating he said that?

I don't want the current guy I am dating to leave because of it. I don't know how to work on it without a partner. My ex had never kissed anyone before and he was just so fast at it and that's where I picked it up. What should I do? I am so nervous I seeing him today and the anxiousness of the anticipation of a kiss happening is driving me insane.
