Is it a bad sign if there is no kiss on the first date?

It's not bad at all. But if you don't kiss by the 5th date, that might be a bad sign. No, don't worry about it. You may want to expect one by your third date, though.

>>depending on ur partner, where shes from and how she is braught up, u may not get a kiss till ur married with her. it all varies with different races and different cultures,

importand thing is not to worry about it, and let it come naturaly for both of you.

the most important is enjoying urself on the date

No, of course not. Just take it nice and slow. Don't rush into anything and plus some women don't like to be kissed on the first date because it shows that you aren't interested in them, but are interested in "other" things.
