Is this a sign that I'm a bad kisser?

I have only ever got off with 4 guys the first time, we kissed the first day we met and then went out for a bit. Second time just once for fun. 3rd guy we got of loads at a party but then he just ignored me when I tried to talk to him. 4th guy, same as 3rd but we got off a lot more and he seem really into it. But after that we spoke but he kind of avoided me when we met up as a group and it didn't happen again. Am I a bad kisser? Do you think I scare them off with bad kissing? If so good techniques? Thanks!
