bilbo, I think you are assuming quite a few things based on this study:
Abstract
PIP: A study in Boston, Massachusetts, and another study in New York City examined samples of pre ejaculate fluid from HIV seropositive and HIV seronegative men to determine whether HIV was or was not present in pre ejaculate fluid. The researchers found macrophages and CD4 lymphocytes in most samples, indicating that HIV was present. The more significant finding, however, was that most pre ejaculate samples did not contain any sperm and those that did had only small clumps of a very small amount of sperm which seemed to be immobile. A larger study is needed to verify these results. If these results are confirmed, they may dispel the myth that pre ejaculate fluid contains sperm. An ongoing WHO/USAID study shows that the pregnancy rate caused by men with 3 million sperm/ml/ejaculation is very low; fertility clinics consider men with a sperm count of no more than 5 million/ml to be infertile, particularly if is there is low motility. The average ejaculation has about 100 million sperm/ml, but about 10 million sperm pass through the cervical mucus, about 1 million make it to the top of the uterine tract, and just about 100,000 sperm reach the fallopian tubes. Thus, only a couple of sperm, assuming motility, would reach the fallopian tubes in the case of the pre ejaculate samples with some sperm, which tended to be immobile (sperm levels only in the 1000s). Thus, the probability of pregnancy is very low if pre-ejaculate fluid enters the vagina. Pre-ejaculate fluid of 6 of the 9 HIV seropositive donors in Boston and 6 of the 14 HIV seropositive donors in New York contained HIV, regardless of symptom status or antiretroviral therapy status. Thus, the risk of HIV transmission may be higher than unplanned pregnancy, so people should use condoms before the penis enters the vagina, mouth, or anus.

Some of what you said is true but that is only the case if preejaculate is the only issue, not ejaculate/ semen also AND the man has not had sex recently or has urinated since then AND pregnancy is the only concern AND that anyone who uses the pull out method is conscientious enough to take all of these things into consideration. You also failed to note the finding that HIV is present in preejaculate and can be transmitted to a partner. Yes, some people can use the pull out method longterm successfully but I believe that the vast majority of people cannot. So I don't think you should be downplaying the risks of relying on the pullout method. Some of the previous posters are obviously unschooled on sexual matters and I would hate for them to think urinating before sex would make it impossible to impregnant a wopman. As you said, the last minute pull out often leads to accidents. And the pull out method does nothing to protect users from STDs and STIs. Additionally, all the people I know of who use the pull out method are teenagers and teenage males rarely have enough control to be able to manage the pull out successfully. They are also more likely to have the energy for a second round of sex before the need or thought to urinate occurs, which means some sperm will be present in their preejaculate. Even you, the "pull out master", and your friend have had scares. So what makes you think that others won't have the same problems???
