I wonder if it's not talked about because of the stereotypes associated with men in America. Men are thought of as the aggressors in sex, the one's that are always ready ect. I've almost finished the book "Sex at Dawn" and one of the last chapters talks about this in some detail. Crap, now I can't remember what it says off the top of my head. hmph.

Maybe because the people they are with also have low sex drive and don't care.

"I wonder if it's not talked about because of the stereotypes associated with men in America."

I'd say Nothern Americans and Europeans might even be more open discussing this than men from, let's say, Latin America.

Sometimes I wonder if it's mostly because they no longer feel any attraction to their partner...

Various people in relationships I know soon find that the partner they chose originally gradually morphs into the kind of partner (physically) that they didn't want, and thus the sex drive diminishes, if not evaporates completely.

If there's no physical cause, why does the sex drive decrease? I find sex far more interesting now that the biological imperative is gone.

"If there's no physical cause, why does the sex drive decrease?"

This question assumes that the sex drive isn't naturally low to begin with. And there can also be psychological causes like stress or depression that affect libido, not to mention underlying medical conditions or medications that can affect this.

People do wind up partnered with someone of unequal sex drives. Whether or not they actually *talk* about it is a different story - this is people's sex lives and a pretty private matter so I can imagine not everybody is keen about divulging issues involving sexual dysfunction for obvious reasons.

As far as loss of attraction to the partner, Nota had a thread about a friend of hers going through this a while back with her husband - he had medical issues and it just wasn't happening - it wasn't an attractiveness thing at all. It bums me out when a guy has problems "down there" and blames it on the chick. This can certainly be a part of the issue, but I'm also inclined to think the guy just might be using this as a way to not take ownership of the problem - it is *his* penis, after all! Women are typically very quick to blame themselves in situations like this and think their attractiveness as a woman has diminished even when this is not the case. I mean, what could possibly be worse than your partner not wanting to have sex with you? It gets internalized - surely it must be *you* due your weight gain/aging/post pregnancy body/etc.... I think this can make a woman feel very bad about herself uneccessarily when the issue might not be about her at all.
