It's Harder For Women To Transmit HIV to Men
Part of the Magic Johnson narrative around his HIV is that he contracted the virus from heterosexual sex, which is still hard for some to believe. It even leads them to question the basketball legend's sexual orientation. It is strange that magic found that one woman with HIV that hasn't die yet being she was a groupie with less satisfactory medical care then him. Also a groupie would be on call for other sports events with NBA players, rappers, and the R. Kelly's of the world but it seems to be only Magic Johnson that got it while others seemed to have gotten Herpes like allegedly R&B singer Usher.
Here's the real deal: Yes, it is biologically harder for a woman to transmit HIV to a man during unprotected vaginal sex compared with unprotected anal sex, but that doesn't mean it's impossible -- or that it doesn't happen.
While it is more difficult for a woman to give a man HIV, it’s not impossible. Compared to the vagina, there are fewer areas on the penis where the virus can enter the body. HIV can enter through the opening of the penis (urethra), where there’s a delicate kind of skin called a mucous membrane. The virus can also enter through cuts or sores on the penis.
It’s true that a woman is at higher risk of getting HIV from a man, because the vagina is all mucous membrane—which makes a larger area for HIV to enter the body. Also, semen may stay in the vagina for days, which increases exposure to the virus. Harder doesn't mean impossible.
