Re-read my reply above. It should be clear there was no risk, as long as neither of you had any other partners at the time. Even if there were other partners, if those also only involved oral and not anal sex, the STD was very low, but not zero.
I'm a guy And so is my friend. When I made my profile I clicked the wrong gender
My question is how does this relate to teens who aren't gay. Like when I was young at that age I did that kind of stuff with just one other boy. We never thought of either of us as gay. We did oral sex off and on for about 2 or so years but we never did anal. Never thought anything of it. Both have girlfriends now but me and him aren't friends anymore. We aren't gay at all. I'm almost 20 now. What's the risk for that?
What you saw on the internet is correct: STDs are far more common in MSM than women or straight men (10-20 times higher for gonorrhea, up to 100 times higher for syphilis and HIV). There are three main reasons: 1) Many MSM go through times when they have sex with many partners, often anonymously, which means those with STD can't contact their partners to make sure they get treated promptly. 2) Some STDs are especially easy to transmit by anal sex, including HIV, syphilis, and gonorrhea. 3) STDs in the rectum and oral cavity often cause few symptoms, so infected people often aren't treated quickly. There are other reasons, but those are the main ones.
In other words, it isn't being gay or just have sex with other men. It's the kind of sex, how often, and with how many partners. Age has nothing to do with it, except that younger people usually have had fewer partners.
If neither of you has had sex with anyone else, no STD is possible. But once either of you starts hooking up with other guys, especially for anal sex, your mutual risk will skyrocket.
If you haven't been vaccinated aginst hepatitis B and human papillomavirus (HPV), do it now. And I urge you to get into the condom habit for anal sex, even if you are monogamous with each other. When either of you moves on to other partners, plan to avoid unprotected anal sex with other men, and never have sex (even safe sex) without first discussing HIV status with each other. Follow these rules and you'll avoid most STDs -- most importantly, HIV. Don't follow them and you can expect to have lots of STDs and to catch HIV someday.
