To think that on average women ARE less keen on casual sex? (NB. I have no objections to casual sex if ethical)

I don't assume anything about anyone, and I certainly don't assume it just based on their gender. That's literally my point.

Who said anything about hard and fast rules?

"If I meet one man and one woman, I predict that the man will have a higher willingness to have casual sex than the man" is a statement with very high predictive power.

You can go around assuming all the lesbians in your life are desperate to go dogging every night if you like. Let me know how your invites turn out...

I'm still not sure why you seem to be so keen on discovering hard-and-fast rules based on stereotypes, averages and evopsych bollocks.

Who cares about the average man and woman? They don't exist. The individual men and women in your life exist and every permutation of sex drive you can think of will be among them.

Trying to fit people into cliched boxes is fairly useless. Sexuality is interesting because most people are exceptions to the cliches in some way.

How is that patronising?
They enjoyed casual sex when they were in their 20s and now in their 50s they're enjoying it again.
It's a turn of phrase, no negativity implied.

I would have thought that the most distinct sex difference would be the propensity to violence, be that rape or other sexual violence. Female rape and sexual violence stats must be a tiny fraction of male.

Compared to men yes women as a collective like casual sex less.

Not sure anybody disagrees with that.

Willingness isn't the same as actually having it! You can also look at the difference in gay male sexual behaviour - much more organisation around stranger & casual sex because there isn't the barrier of women's greater disinclination to engage in that kind of thing.

Who are all these men having casual sex with then..

I think I remember the thread you are talking about and I'm wondering if you are the same person because the OP of that thread shortened certain words down e.g "obvs" and you do that too.

Willingness to have sex with strangers is THE most consistent and replicable sex difference.

If you are referring to me and assuming that I “denigrate women’, that is quite some reach.

I find the idea men or women having casual sex completely bizarre. I would expect there to be a relationship in place before having sex. But then I’m more about mental connections rather than just carnal endeavours. Actually more than bizarre, I find people who do this rather loose. Not my kind of person.

I find it more misogynistic to denigrate women for "catching feelings" as if this is weak behaviour.

Ive not heard the argument that women would still want sex with their husbands, I've been married and I've gone off sex with my husband due to their selfish ways/lack of communication etc, def not gone off sex itself as I discovered when I left him and had lots of sex!

Im not entirely sure what I think either. But I do know that the 'boys will be boys' testosterone argument is used to excuse poor male behaviour. That raises my suspicions, as generally people like to use a biological excuse for choosing poor behaviour if its available.

I think it's probably right, but I think it's just societal pressure internalised, if I were to guess. Girls at school who let one or more boys touch them: slags. Boys who touched multiple girls: heroes. Trite stuff from nans and mums about boys not buying the cow if they can get milk for free, etc. It's all bred into girls from a fairly young age in a way it isn't for boys. That has to be having an effect: girls come to see sex as something they should be doing for love, in serious relationships, etc, and there's a moral weight to not doing so. I know plenty of women who have sex very casually but they're much more apologetic about it then the men I know are.

For me, the question is how can we determine sex drives. How can we strip away the centuries of slut shaming women, men feeling entitled to womens bodies, male violence and the resulting fear in women, the low rape comviction rate etc? Thats what we would need to do in order to look objectively at sex drives and its not possible. The nearest way to strip out those factors is possibly in a long term relationship. Where my experience tells me that women have higher drives and get bored with one man more quickly than men get bored.

Think this is crucial - it can take time to show a man what you need to orgasm a ONS is not always conducive to this which is why FWB can be more attractive for women - plus safety but it is still ‘casual’ sex I.e. sex for the sake of sex

Most of us are just commenting on our own experiences and not with authority. Based on that, my pretty extenstive experience informs me that men will make use of their dicks whenever possible (unless medical reasons come into play). There aren't many female rapists, pedophiles, sex pests or offenders are there.
