Depends upon how you define "gay sex". A couple of lesbians are less likely to engage in anal sex than a heterosexual couple; does this make "heterosexual sex" more risky? If anal sex with a condom is less risky than vaginal sex without; does that make vaginal sex more risky?
Some gay men think that it is heterosexual men who are obsessed with anal sex, because the "coin of the realm" in their weird little world is the blowjob. To which I say "Don't play coy you little bitch! I know you are an ass bandit!" JUST KIDDING!
