Most of the more serious STDs (such as AIDS) are transmitted through bodily fluids - primarily blood, which can pass on the infection, or receive it through the open wound, no matter how microscopic it may be. As the anus is very prone to bleeding - especially when it's invaded by a foreign body, such as a penis or a dildo, etc., which is why it is so stereotyped as being a Gay disease, because of the higher likelihood of their partaking in Anal Sex than that of a Straight person. Condoms are invaluable as a basic 1st line protection, but are not, by any means, guaranteed, as infections can also be passed orally - even by kissing (although the risk level here is obviously much lower). In short, there's no such thing as 'Safe' Sex - just 'Safer' Sex (not counting solo masturbation).
Congratulations you can tell a bullshit story over and over. That doesn't make it any less bullshit. C/S, Rev J
To have anal sex either with or without wearing a condom would mean there would still be a chance of some poop getting on it & the unpleasant smell it causes. It would be cleaner & safer to use protection even if the other person had cleaned themselves out beforehand but there's still that chance of poop that doesn't get removed unless an enema is used beforehand.
Unprotected sex with a non-monogamous partner is just suicide, anal or vaginal, but more so for anal. I hate using condoms and LOVE anal. I mean could you imagine asking some girl on a random hook up if u could cum in her ass? I cum in my wife's ass 80% of the time we have sex. If I were sleeping around I would need to learn the jedi mind trick to have anal 80% of the time. Pussy is everywhere a nice tight juicy big ass to stick your dick into, is not. I don't think I could cheat on my wife if I wanted to, I can't even get my dick hard when I know I'm gonna use a condom. Even most most women that are into anal usually won't let you hit their ass on a one night stand ESPECIALLY without a condom.
The only times I've gone Bareback have been with those I know I can trust but, regrettably, this is not possible with NSA one off casual partners. However, to be honest, when it comes to Anal, things are so tight that I've never really noticed much difference.
