If you show up for a date with a police officer, you're going to get arrested regardless of what you do or don't do, say or don't say... Being cautious in text beforehand isn't going to help you at all. Proper screening is the only safeguard.
Personally, I just find suggestive language annoying. I think clients who aren't serious about meeting attempt to get free entertainment through text & calls, versus actually scheduling and paying for our time. Based on my experience, guys who talk like that are usually time wasters. I won't acknowledge a potential client unless he has a respectful, professional dialogue.
I only morph into a whore after my envelope hits the table.
