A real straight man would suck another man's dick no problem. When I'm in the club and a guy asks if I can get him off I say "sure dude, it's not like I'm gay or anything."
LOL sure dude. Just don't take a picture afterwards like last time. People keep calling me gay after that, and I'm like naw dude, I'm just horseing around with my bro, you know how it is.
