you dont have to ASK someone to refrain from touching you!
you TELL them and if you want to be nice at first you simply
say, i am not comfortable with your touching me, so please
be mindful of that, thanks
and the thing is... ANYTHING they might say to dismiss your
boundary means they want to control the situation....
"oh, i am just a touch-y person" yada yada....
ask, my ass!!! set your boundary and defend it!!
