bad kisser

I'm petrified I'm a bad kisser, my boyfriend hates that I never want to but it's because the first time I made out with a guy (around 5 month ago) it was so sloppy and gross, I remember thinking that I couldn't wait to go home so I'm literally scared that I'll do that to him. I don't do anything weird, I'm not sloppy and I don't force all my tounge down there I just can't get over this fear
