It asked, "Why do (some) women sleep with one guy the day they meet , but waits until commitment with another?"

One woman answered with this:

Circumstances.

That's it, that's literally it.

Did you [the guy] meet on a date, or out on the prowl looking for a lay?

Did the guy express interest in having sex right away (this is a big one)?

Were you drunk (this is a HUGE one)?

It comes down to this for me.

When I think of past "hookups" turned "FWBs," all of them I met at a party or house party or boozy social gathering or dance party or a fun social gathering. Typically these are guys within my social network and not complete strangers. They are usually friends of friends of friends who I've seen out and about at other social gatherings.

I'm not walking around my life bursting to the seams with "lust."

And so, if I happen to indulge in an impulsive lust-filled moment, 9/10 my environment dictated it. Meaning I was at a dance-oriented party where I ended up vibing seductively and rhythmically to the beat of the drum with a guy for a good while which, yeah sure, will likely lead to feeling lusty. OR I was in a tipsy and hyper-social fun environment and without fail I feel lustier when wine and/or shots are involved.

So for the men who are very much confused as to when and where "hookups" happen, are you out doing fun social things????

If you desire to be the "hookup" guy, catch her in a "hookup" environment whilst also being playful and fun. The environment and/or substances do 90% of the heavy lifting here.

If you are going on a "romantic first date" with someone and taking it all seriously, she is going to take it seriously. And "hookups" aren't "serious."

For me personally, "hookups" don't happen after a first date. If I'm on a first date with a man who I'm crushing hardcore on, I want him to be more than a "hookup," so I am not going to encourage anything outside of that. In fact, every man who has pursued me seriously was the one who was intent about the first date ending with a kiss and that's it. Which is really sexy, because I'm left thinking about that kiss and wanting more.

That's also key. Those men knew I was super into the kiss and so didn't feel as though I wasn't sexually interested in them. Context wasn't lost on them.
