Women have a higher risk of getting HIV from vaginal sex:

 

 Women are more likely to get HIV during vaginal sex than men are for several reasons.

• The vagina has a larger area (compared to the penis), that can be exposed to HIV-infected semen.
• Semen can stay in the vagina for days after sex, while men are only exposed to HIV-infected fluids during sex. Semen left in the vagina means a longer exposure to the virus for women.

Having untreated sexually transmitted infections (STIs) makes it more likely for a person to get HIV. This is especially true for women. Small cuts on the skin of the vagina are hard to notice but may allow HIV to pass into a woman's body.
