A Riddle: On A Kiss

What thing is that, nor felt nor seene
Till it bee given? a present for a Queene:
A fine conceite to give and take the like:
The giver yet is farther for to seeke;
The taker doth possesse nothing the more,
The giver hee hath nothing lesse in store:
And given once that nature hath it still,
You cannot keepe or leave it if you will:
The workmanshippe is counted very small,
The labour is esteemed naught at all:
But to conclude, this gift is such indeede,
That, if some see't 'twill make theyr hearts to bleede
