舔阴后戴套性jiao的风险
--------------------------------------------------------------------------------
Hiv transmission doesn't stand a chance of happening via female genitals to mouth - there are just too many obstacles on the oral route.
hiv传染不会通过女性的生殖器官-嘴这种方式，因为这个途径中有很多障碍阻止传播。[/color]
The first obstacle is the mouth itself. The mouth is a veritable fortress, standing against all sorts of pathogens we come into contact with every minute of our lives. It's a very hostile environment and saliva has been shown to contain over a dozen different proteins and enzymes that damage hiv.
第一道障碍是口腔本身。口腔可以比作一个坚实的城堡，伫立在前线对抗我们生活中接触到的各类病原体。对于病菌，口腔是一个很不友好的环境，并且包含许多不同的蛋白酶来对抗hiv。
Hiv is a very fragile virus - literally. Its outer surface doesn't take kindly to changes in its preferred environment; slight changes in temperature, moisture content and pH levels all damage the outer surface. Importantly, it needs this outer surface to be intact before it can latch onto a few, very specific cell types and infect.
hiv是一种非常脆弱的病毒。该病毒对周围的温度湿度和PH值的变化非常敏感，轻微的变化就足以摧毁病毒的外壳。关键是，该病毒需要其外壳来倾入所能被感染的细胞。Which leads to the second obstacle. Hiv can only latch onto certain types of cells, cells which are not found in abundance in the mouth.
这就是第二道障碍。hiv只能侵入一些特定的细胞阻止，但是这类可被侵入的细胞组织在口腔中却并不多。The third obstacle to transmission this way is having hiv present in the first place. The female secretion where hiv has been shown to be present is the cervicovaginal fluid. This fluid is actually a thick mucus that covers and protects the cervix.
第三道障碍是目前的研究发现女性分泌物中的高病毒量hiv液体主要在子宫颈部位存在，即存在在宫颈分泌出的分泌物中，这种子宫颈分泌物主要用来保护子宫颈口。
The fluid a woman produces when sexually excited comes from glands located on either side of the vaginal opening. I have yet to discover one shred of evidence (and believe me, I've looked) that shows this lubricating fluid to have any more hiv present than other bodily secretions such as saliva, sweat or tears. Saliva, sweat and tears are NOT infectious fluids.
而女性兴奋或高潮所产生的分泌物主要通过位于阴道两侧的特殊腺体（巴氏腺）分泌。我通过查阅一些医学资料发现这类分泌物所呈现出的传染性等同于唾液，汗液和眼泪。而唾液，汗液及眼泪是不会传染hiv的。
So there you have it. Once the results of the serodiscordant studies* started rolling in, what we know about hiv transmission on the cellular level was validated. The only people who were getting infected were those who had unprotected anal or vaginal intercourse. Period. One of the three studies went on for ten years and involved hundreds of couples. That's a lot of nookie.
所以，我们所了解的传染途径是无保护的阴道性jiao和刚交。这是通过十多年的包括对上百对夫妇的研究得出的。*There have been long-term studies of couples where one is positive and one is negative. In the couples who used condoms for anal or vaginal intercourse, but no barrier for oral activities, not one of the negative partners became infected with hiv. Not one.
并且，通过长期的对一方感染另一方未感染的夫妻经行的研究发现，这些夫妻只在刚交和性jiao时使用安全套，而口交行为是完全无保护的，但这个研究到目前都没有发现未感染的一方被传染。Use condoms for anal or vaginal intercourse, correctly and consistently, and you will avoid hiv infection. It really is that simple!

关于否定旧金山一篇报导8%口交风险的报导 2002年
包含了两大长期实验，一个是美国的，一个是西班牙的
On average, the men in the study had had receptive oral sex with three different men in the past six months (range 0 – 400). The overwhelming majority, 98%, of oral sex was without a condom and 35% of men reported getting semen in their mouths, 70% of whom swallowed.
This study dramatically contradicts a much reported investigation, also conducted in San Francisco, which suggested that as many as 8% of all HIV infections amongst gay men were due to oral sex. The conclusions of this study were subsequently undermined, and a recently published Spanish study involving heterosexual couples where one partner was HIV-positive and the other negative, concluded that not a single case of HIV transmission could be attributed to oral sex in a ten year period.
美国的实验是几百名有感染和未感染的男同性恋，在6个月内，进行0-400范围次数的口交，其中35%的人射精在口中，其中70%吞下精液。结果无一未感染的人在实验后被感染。
西班牙的实验是，很多对夫妇（都是一个被感染一个健康）长期的进行无保护口交（包括吹和舔阴），戴套性jiao，长期如此，实验结果无一健康的伴侣被查出感染。
文章比较长，有时间再翻译吧。英文好的朋友可以看看

In June 2002, a study conducted amongst 135 HIV negative Spanish heterosexuals, who were in a sexual relationship with a person who was HIV positive, reported that over 19,000 instances of unprotected oral sex had not led to any cases of HIV transmission.3 The study also looked at contributing factors that could affect the potential transmission of HIV through oral sex.
