Yes, generalisations are an issue. Statistically speaking there may be more men with a high sex drive than women, but to say men have a higher sex drive than women is a different statement, the former suggests that as a man I should have a higher sex drive than a woman, but the latter suggests that more men have higher sex drives than women. There could be plenty of extremely horny women and plenty of men who enjoy sex, but have a very low sex drive.
I suppose it's semantics really, but still I think the distinction is important for the sake of clarity.
The problem with human psychology is that you can't generalise. One of the problems with psychological studies is that you might find things stack in your favour statistically, but on a more individual level, your answers might not even be applicable. Many do try and universalise psychological studies (generally people who aren't psychologists), but individual differences tend to be the reason why there's never a one shoe fits all approach to psychology. This is kind of the reason why when using a psychological theory in the 'should parents hit their kids' discussion I didn't have much of a leg to stand on, whilst the psychological theories had a lot of support for me original argument, but it was nothing that could really be universalised, which is why when faced with additional data I changed my stance as I saw it to be more substantial, though with the findings of both studies are not wrong, it just means they apply to different groups. I see it as being the case here.
The human brain is highly complex and highly variated. It'd be a very boring existence if it weren't.

And of course, if you horny devils like your one-night stands and having a sex driven relationship, you're welcome to it, it doesn't make you 'bad' people nor does it make you lesser. Heck, you sexy beasts might be in the majority. But hey, its your lives, so shag to your penis' desire if you must.

And I'll sit here writing bad poetry and using the moon in lame metaphors to tell HAL how I would turn gay for him.
I wonder, what's a good rhyme for Lark? Not, Tony Stark, because I'm a one-man straight guy.
[edit]
I'd be interested in knowing how much of our 'sexuality' or lack of is influenced by culture, society and even the media, does the representation of sex given to us affect our attitudes towards it, or does it even affect our sexual drive to a degree?
