How important is kissing? A question for women under 30 (3)

I have a question for the younger people here, in particular women under 30. Suppose you met a very attractive man, you started dating and found him fun to be with. He was intelligent, sensitive, kind, great sense of humour, etc. Clearly he had all the qualities you were seeking and after several dates you shared your first kiss. However, that first kiss didn't do it for you. My question is, would that be a deal breaker for you? I'm asking because I know someone who had been dating a girl for about a month and they had that kiss which was great for both of them. But she told him, "It's a good thing you are a good kisser because if you weren't, that would be it". He was quite surprised, but she said that she and her other female friends all feel the same, if you are not a good kisser, you're done. My thoughts are when you are in a new relationship it is a new experience for both of you. I think you have to become acquainted as to what feels good for you both or rather let each other know what you like. I can't imagine dropping a guy just because he is a bad kisser. But what do I know, I'm just a little old lady who lived through the 60's which was the age of free love, so anything went. Of course if someone is licking your whole face, sticking his tongue halfway down your throat, you need to give him some lessons! But I'd be interested in hearing from women of any age about how you feel about this? Would you drop someone who had everything you want just because that first kiss was not good? Doesn't practice make perfect?
