我会通过阴道性交感染HIV吗？

是的，无论哪一方，都有可能通过阴道性交感染HIV，尽管与接受性肛交相比，阴道性交传播HIV的风险较低。

当女性与HIV阳性伴侣发生阴道性交时，HIV可以通过阴道和子宫颈的黏膜进入她的身体。大多数女性感染HIV的方式就是通过阴道性交。

男性也可能通过与HIV阳性女性发生阴道性交而感染HIV。这是因为阴道液和血液都可能携带HIV病毒。男性通过阴茎的尿道口（即尿道）、未切除包皮的包皮，或是阴茎上的小割伤、刮伤或开放性伤口感染HIV。有关如何降低通过阴道性交感染HIV风险的信息，请参考预防相关问答。

Can I get HIV from vaginal sex?

Yes, either partner can get HIV through vaginal sex, though it is less risky than receptive anal sex.

When a woman has vaginal sex with an HIV-positive partner, HIV can enter her body through the mucous membranes that line the vagina and cervix. Most women who get HIV acquire it through vaginal sex.

Men can also get HIV from having vaginal sex with a woman who is HIV-positive. This is because vaginal fluids and blood can carry HIV. Men get HIV through the opening at the tip of the penis (urethra), the foreskin if they are not circumcised, or small cuts, scratches, or open sores anywhere on the penis.
