Why does depo increase your chances 40 percent for contracting hiv? what would then be my chances with risky behavior with a straight white man

Be careful: 19 year old young woman with concerns about HIV and depo. Be very careful when choosing a sexual partner and don't be afraid to discuss beforehand. That being said, don't worry about risk retrospectively. Instead, take a test for HIV. A young woman like yourself also needs to be screened for chlamydia and gonorrhea according to the USPST. Be confident and careful. Go to OB/GYN or clinic & test.
