Have been on three dates with this amazing guy, chemistry is going great.. when is it ok to kiss?

We’ve held hands and have held each other but haven’t kissed just yet.. wondering if it’ll be ok on the fourth date which we’ll go on Saturday - we’re gonna do a safari ride then carve pumpkins after : ) on this lovely hill on the lake
