I think I'm pretty similar to you in this department, I won't let them take the piss or anything, but I do find it hard to be assertive..
I've never told anyone to fuck off (yet
), although there's been many times I've wanted to!!
Even telling a guy (I'd seen him before and he was in my phone as "rough, dirty, don't see again") that he'd probably be better
booking another girl, as I offer GFE and he was talking about "fucking me hard etc. etc...", was quite hard for me, but I was glad I did
it coz I know he won't bother me again.
As long as you tell them politely and reasonably you don't want a booking with them, I think we're doing fine, and we're assertive enough!
Another thing I've had to learn is that I can't wear myself out on busy days and try and please everyone by giving them ALL a booking,
leaving me totally fucked for the next few days from the stress alone!
Now I'll just tell them, sorry, but I'm really busy today, if you'd like to make a booking for tomorrow that's fine..
If they really want to see me they'll get back to me or take that booking for the next day!
