8、 所有人造的安全套在预防HIV方面都是同样有效的。无论你的性交对象是什么人，只要你全程正确使用安全套，中途没有滑脱或破裂，你就没有感染HIV的风险。 有一个很具讽刺意味的现象是，在网上，担心与性工作者发生带套性交而感染HIV的人群，远远多于那些与陌生人或网友等发生无套性交（一夜情）的人群。而事实上，后者才是真正的感染HIV和性病的“高危”行为。 性工作者使用安全套是为了保护她们自己不被顾客感染， 而不是为了保护你！ 她们比你 更有可能感染 HIV，因此她们更懂得如何保护自己（为了混口饭吃，犯得着拿生命开玩笑吗？） 。事实也证明，正确地、自始至终使用安全套的性工作者是没有感染 HIV 的。在美国内华达州的某些地区，性产业是合法的。由于强制性地使用安全套，加上性工作 者被培训过如何正确使用安全套， 在华达州政府对正规妓院的性工作者每个月的例行检查中，已经多年没有发现一例HIV感染者了。一名坚持使用安全套的性工作者，感染 HIV 的可能性不会比一个“普通人”要高！除 非对方是静脉吸毒者（通常会与他人共用针头） ，或者对方生活在一个HIV高流行的第三世界国家，否则你遇到的性工作者感染 HIV 的几率低于 1/100. 综上所述， 所有 “因与性工作者发生带套性交而担心 HIV 感染” 的焦虑都是无根据的、不必要的。在你焦虑不安时，仔细阅读本文的内容，停止你的胡思乱想与惴惴不安吧！
Protected sex appears to be the most popular concern in this forum; at least a third of the questions here relate to protected sex. The vast majority of concerns about protected sex relate to situations with sex workers. You are not going to contract HIV from protected sex. Here are some facts about condoms: 1. Condoms work by protecting your urethra (or, if uncircumcised, foreskin) from contact with infectious fluid. 2. It makes no difference if the condom only covers a portion of your penis: if the head is covered you are protected. 3. Studies with serodiscordant couple, monitored over several years, have proven that correct and consistent condom use prevents HIV. 4. If you wore the condom throughout the entire act of intercourse, with no unprotected vaginal or anal penetration, you used the condom correctly. 5. An intact condom is 100% biologically effective in preventing HIV transmission. 6. For the wearer, condom breakage is catastrophic and very obvious. Unless you see your penis covered with what looks like a fringed hula hoop (i.e. the remnants of the condom), your condom DID NOT break. 7. There is no such thing as 'invisible holes' in condoms. 8. All synthetic condoms on the market are equally effective in preventing HIV (latex, polyurethane, etc.). It doesn't matter WHO your partner is: if you used the condom correctly and it stayed intact, you DO NOT have an HIV concern. It is ironic that posts about protected sex with CSWs vastly outnumber posts about unprotected sex with bar pickups and other one night stands, when the latter is a far riskier situation for HIV and (in particular) STDs. CSWs use condoms to protect themselves from YOU, not the other way around. They are at far greater risk from catching something from you, than you are from them, and real life evidence shows that CSWs who use condoms consistently and correctly do not catch HIV. Prostitution has been legal in certain parts of Nevada for years, and NOT ONE prostitute working at a legal brothel in Nevada has ever tested positive for HIV as a result of their monthly, state-mandated screening. This is because condom use is mandatory and they are trained to use them correctly. The likelihood that a CSW partner who uses condoms consistently with clients has HIV is
probably no greater than that of a 'civilian'. Unless you are picking up prostitutes that work the streets to support an injection drug habit, or live in a third world country with high HIV prevalence, the chance that your CSW partner has HIV is less than 1 in 100. From what I have outlined in this post, I hope you can see that there is no basis for all the anxiety that is being generated about protected sex with CSWs. Please consider this before you decide to post in this forum.
