How does HIV spread to heterosexual males substantially if the risk for getting it from an encounter is less than 1 out of 1,000?

Question

So they say the rate for vaginal sex is [less than 1 out of 1000](https://www.hiv.va.gov/patient/faqs/risk-of-unprotected-sex-with-woman.asp). So how do most heterosexuals get it. Is it through anal sex or drugs and would that man a heterosexual that has vaginal sex has a negligible chance of getting it? Apparently if you’re circumsized too your risk is much less as well?

Answer 1

* heterosexual guys aren’t always heterosexual.

* anal sex is more risky because it is not as elastic, and it makes contact with blood more common.

* One in 1000 is not very uncommon if you have a lot of sex. It only happens once, and then you can spread it around.
