Safe Sex Question About "Pulling Out"

[whipped guy]

...one should not presume statistical significance.

That is why a course in statistics is usually part of any health professional's training... Upon reading the literature, one must be able to determine that any given study was indeed conducted in a manner that would deem it statistically significant and therefore valid... and if for no other reason than it is possible to manipulate the numbers to produce any desired result.

This may be (probably is) a stupid questions but is pre-ejaculate and ejaculate the exact same material. If it is not (or even if it is) is there the same concentration of the virus in both. Would that make any difference at all regarding pulling out or fully ejaculating? Thanks.

No this is not a stupid question at all. I believe I have read that pre-ejaculate does contain HIV virus. Nevertheless, the information contained in the abstract above seems to indicate that couples who were irregular in their usage of condoms and who routinely practiced coitus interruptus had no transmission of the virus. I realize that we are all concerned with safe sex and how the HIV virus seems to be spread, but that study listed above seems to be saying that at least for the duration of the study in question there was no sero-conversion among those couples practicing coitus interruptus. Doesn't anyone else find it extraordinary that apparently no other study has been published that contradicts this finding? I want to encourage responsible behavior as much as the next guy, and yet this study seems to offer at least the appearance of some wiggle room.

Pre-cum comes from Cowpers' Glands, and cum mostly from from the prostate (there is obviously also some sperm from the testicles also, but I can't imagine that vasectomy would affect HIV transmission much). Pre-cum has been shown to contain HIV in this Lancet study: http://www.aegis.com/news/ads/1992/AD922464.html . So, no, pulling out before cumming is not safe.
