This is a very delicate manuever which takes years of experience and lots of practice! In reality, it almost takes being 'born into' this lifestyle but some people don't understand that they think it's simple! You make it look easy though Sweetoes dear! Keep up the good work!
You certainly have got the smile down pat! That in itself shows the dedication it takes to accomplish what you do!!! Really my friend, I truly admire you always! Beautiful! :)
