OK, lets step back and take a breather!
Think back to the first time you did oral sex. Was it something you just jumped into and did immediately? Did you have to think about it a while? Wasn't it something that you had some aversion to at first? I know it was for me. I had to think about it and had to become aclimated to the thought of doing it. When I did finally do it, it took a while to get past the hair and the humidity and the scent and the things in my head. It took a few times of coming close and not quite getting there before I actually did it. Of course, once I did it, it was much easier after that and finally became a normal part of making love.
The first time doing it to a man will be the same way and if the woman is not familiar with intact or circumcised, she will have no different feelings for either one. If she has already done it on a circumcised penis, she's going to have to go through that same trepidation again, just not to the same extent as the first time. Those who say they will not do it are just ignorant of the foreskin or didn't care for the man enough to get past that initial aversion.
Granted, there are some men who do not practice normal hygiene just as there are some women who do not practice normal hygiene. Somehow I have been able to sort out those women who don't and it wasn't difficult. There are plenty of signals in their hair, clothing and general grooming. I can't imagine that it is any more difficult to sort out the men who don't practice normal hygiene.
I have never been with a woman who was not scrupulously clean and I can easily imagine if I were female, I would not have been with a man who was not scrupulously clean either. That being the case, if I were female, I can't imagine I would have any more trouble with the intact male anatomy that I had with the intact female anatomy as a male.
