Ah, the eternal question, to Kiss or not to Kiss.
as Ummmm said, the guy is going to be in the same position as you. As a result both of you are nervous and the thought of the impending goodnight kiss situation can often ruin your evening.
If the first date has gone well and it is apparent that you are going to see each other again then I think a small kiss is acceptable. Save the good stuff for the next time. However, and I've recently discovered this, it is also perfectly fine to just hug and agree to see each other again without one or both parties running away screaming that you're not interested in them.
It shows that you had a good time with them, that you're interested in them but respect yourself enough to not give up all of the goods on the first date.
Anyone will respect you for it and look forward to the next date all the more.
Good luck
K
