I don't think your complaint is abnormal or weird or different or rare. To get right to the point there are many men with very sensitive penises and it's very common. Even though you claim bbbj is the best for sex you have not included if this is also an issue for you when you have sex with a non paid person .
Even though you might think there is no difference either way for many men the nerves and the mental aspect can play a very big role with different degrees of sensitivity .
My suggestion is to pick an escort you like within a reasonable price range you can justify spending multiple dollars on her service This escort doesn't have to be the prettiest or the best in shape this requires thinking with your big head .
Does this woman actually understand how sensitive you are ? Does she listen ? Is she very adept at reading body language and feeling your vibe maybe even before you do ? These are the kinds of escort skills that are really worth the money and repeat business . Once they show you how they cure this issue you will have greater clarity on wether you should keep a condom on for all or partial time for your bj or maybe she will have different ways to help you relax and enjoy the experience without pain .
I highly doubt it's the escorts your seeing that are tearing your poor dick up You need a cock specialist and non of them fit that bill .
I wish you all the best in solving your mushroom cap sensitivity
