Consensus is that MSM are somewhere between 20-26 times more likely to contract HIV then other adult men. How much of that is biological and how much is cultural (e.g. in countries where homosexual sex is criminalized, access to healthcare and prophylactic medicines are likely less available) is definitely up for debate, and it of course does not mean that a straight man cannot contract HIV.
Fun fact, I’m O- and a gay man. I used to go down to those blood drives and flash my medical card. They were all very excited to take my blood, and then I said I was gay. The sad looks fuel me to this day.
