I went to see an EE once. Not my usual fare but one of the Somali WGs had let me down and I had no plan B - I was still green. Anyways, the EE WG said she would see me and left me to strip. When she returned and saw the size, she flat out refused. In that particular case, it wasn't about race. I was like, babes, its after midnight, you've been working most of the day anyways, and she was like yes, but I'm working all night and if I fuck you now I'll be in pain the whole night. I got that, and got dressed. That said, I have encountered countless other EEs who refuse to even see me on the basis of my race and the perceived - and in this case true - perception that'll have a larger than usual Charles Dickens.
Just last week I was chatting to a black WG on whatsapp. We were trying to arrange a meet but ended up chatting for 2 hours. Early in the conversation I mentioned my size and she said that was a deal-breaker. She did say she would take a similar sized cock in her private life if the man she was seeing had it, but that would be bareback and have emotions attached and so would be fine. She explained that, at least for her, when she refuses to see big-dicked men, regardless of race, she does so in order to keep herself 'tight' but otherwise no issues with black men.
I think mood sometimes has a part to play. The getting the girl in the mood has a part to play too - but the WG herself has to be in the right frame of mind. I went to see an oriental WG I had seen just the week before. She'd taken the Charles Dickens like a champion and rode it well. It was almost as if she was determined to conquer it. I liked that. One week later, I penetrate her and she starts saying it's too big. Within 10 mins she calls

I'm like - but you fucked me last week! The whole thing turned into a mad situation because I asked for my money back and her brother - in the room next door - had to come in. I suppose they thought that would intimidate me, but i still asked for my money back. But I digress - the girl has to be in the mood.
Usually my punts are long punts. I won't cum in 15 mins, so I don't bother. The longer punts work well for me. I try and see young black WGs. I find some of them quite brave and willing to face down a large penis to get that cash. But I usually get along with them too, so by the time it's time for a pounding, they're already wet and we don't even have to use lube, and then I happily pound away and they take it.
