I don't meet that many very big ones but if I do it is no problem at all. Good girth is great but too much length and I just tell them as nicely as I can that if it hurts in certain positions they either do not fully thrust all the way or we find ways I am comfortable. I really don't understand why any wg would endure pain and bleeding? ! Just because we get paid for sex does not mean we should be hurting and be ruined for the next few hours or day.
One man I have met a few times and is a lovely client, has one of those cocks which is normal width at the tip but gets very much wider along the length, like an ice cream cone! it is rare I have seen them like that and his hurts a bit as he inserts more of it so I just tell him.
Me lying on my front with my legs down and straight and they doing it from behind like that is good because I can put my hand underneath and control a little. I find big cocks rarely hurt me that way.
If any man informs me before we meet that he has a big cock then the meeting is off. Not allowed. I am very strict and do not want to hear of their cocks or see a photo, they are blocked forthwith!
