If from vaginal sex, it's pretty difficult. She would have had to cop a lot of dick. Based on the transmission rates from the CDC (https://www.cdc.gov/hiv/risk/estimates/riskbehaviors.html) theres an 8 in 10,000 chance from unprotected sex that she could have gotten in. And that's if every partner was HIV+ and unprotected. Receiving anal is the most riskiest for sexual transmission. My guess is she was sharing insulin needles to treat her diabetes. Actually it's straight men who would be the least riskiest of catching HIV from sex (and i mean 100% straight, no experimenting, bi-sexual bullshit). Insertive vaginal sex only has an 4 in 10,000 chance of transmission.                 28e2
