I don't think its a matter of "do it" or "don't do it" as everyone is different. You could risk ruining the friendship if it goes wrong. Are you willing to take that risk?

I answered that I would be OK with a friend kissing me, but then again, I grew up going to make-out parties where everyone was kissing everyone else, and yeah, all of my friends had pretty much kissed all of their friends, so it isn't/wasn't a weird thing. Everyone has different boundaries, and I know that most are probably not this free in their kissing! But for me personally, it is OK.
