Well there is a safety issue involved.
English as a first or second or third or fifth language is totally fine for me,
as long as they are able to understand what I'm offering,
and able to communicate this fact back to me.
Do they clearly understand what is on offer and what is not?
Try explaining it."Do you understand?"
"Yes"
"Where are you travelling from?"
"Yes"
"Would you prefer me in a dress or skin tight jeans"
"Yes"
"I don't do bareback"
"Yes"
"What is your name?
"Yes""
And for me the bigee is that I've no idea if they realise that I
1) Have a penis
& if they do know,
2) That there is no way on earth that I will fuck them with it
In my early days escorting, during disrobing, I had a couple of clients freeze, look worried & point, saying
"What is that?"
before making a speedy exit {after I've refunded them}
It really isn't worth the hassle if they don't speak enough language.
I am unable to safely contract with them.
