Being the perfect gentleman that I always am I warn the lady concerned in just enough time to close her eyes tightly shut. (I have verification of this if required).. The last thing I would wish to do is inflict pain and possible lasting damage on my victim ... er...... partner.
But, having said that, if she wishes to swallow, she will find me a most accommodating supplier of that which she craves. hehehehe
I agree with WIshmaster, advance notice is the polite thing to do. Although if they're in contact with the right part of you and know what to sense for, they can tell anyway as the muscles contract just before. Then they can choose.
