Am also struggling to see the logic in this one - but each to their own ideas, its what makes for interesting chat!
Well for me this all started when my female friend informed me of her
flat mate puking up in her toilet and my friend asking her how she could do that
to herself, the reply was "try having a cock shoved down your throat
a few times and you'll get use to it." Truth be known I cant get a handle on it either.
