Well, except under special circumstances, such as their beloved wife asking them for it after performing three soap and water enemas and taking two loperamide, and even then vaginal is preferable.
When guys hear another guy obsessing over buttsecks, a little voice inside their heads is telling them that he’s Gay. There’s nothing wrong with being Gay, but the dude is running a high risk if he should ever find himself incarcerated with people who know this about him.
Since most guys don’t go to jail for long periods, sending this message may not make them cell wives, but it will earn them some interesting nicknames behind their backs. Since anal sex has become a staple of porn, most guys wouldn’t call a dude out for this in public. Almost every one will experiment with it if he gets the opportunity. It’s just that after doing it once or twice, a straight guy will not want to do that again unless he’s into poo. Even some Gay guys prefer heroic man love over anal.
Why this rule is unspoken is due to a combination of middle class male peer pressure and feminist ideology. To say that one hates anal sex, and thinks men who give or receive it past experimentation are Gay paints one as sexually inept and homophobic. Men are afraid to be honest about their level of disgust for it.
For some, because of their hidden beliefs, there is shame after engaging in it at their partners’ request. There’s also suspicion that the woman isn’t enjoying it, which is quite often the case. She feels pressured to copy the porn queens to keep her man, and he feels pressured to copy the studs to keep up with her supposed needs and the other guys who all say that they’ve done it. So at the end of the night, both have had sex like peer pressured puppets, and neither feels closer. If they don’t speak honestly, they both feel pressured to repeat the activity, and slowly the guy starts feeling like even more of a “punk”.
So before you break out the KY jelly and prepare yourself to grin and bear it, ask your man how he feels about anal sex in a non pressure situation first. If he gets a look on how face like he just tasted something bad, and you get the old girlfriend stories of poo, just let that go.
…and if one of his friends’ nicknames is Alfred Sh**cock, the two of you can have fun planning his coming out party.
