Women have no problem whatsoever "pumping and dumping" a guy so-to-speak any more than men.

If that man is:

1) A one-night-stand where maybe there could have been potential but the vibe is just very aromantic because its such a physical and shallow encounter

2) A guy she's just attracted to enough to sleep with but not quite for anything more

3) A guy she's attracted enough to sleep with and see potential with, but not quite attractive enough to beat out either the direct competition of another suitor or the potential competition from the men in her dating pool

She'll have no issue wrapping up the situationship/relationship. The idea women want commitment from the men they sleep with, catch feelings, or are liable to feel an emotional connection more than men after sex is total piffle. Those things only apply if the man is a guy above her league and therefore this tends to be the impression due to female hypergamy.

I've had 12 sexual partners this calendar year. Of those, precisely 6 fell into the categories above. And guess what? They were the most attractive. The top half. One fell into category 1, one fell into category 3 and the other four fell into category 2. Of those 6 I was keen to date and quite possibly commit to three of them.

The other 6 with whom I made it clear I wanted nothing more? They were the least attractive that I was "meh" about. To them, I was a man who didn't want commitment and who "only wanted sex". With them I either directly told them that I didn't see anything long-term, or casually sent texts like "you want to come over tonight and have a little fun?" so that they were well aware that I didn't see anything serious with them.

And that's the reality.

If a man is so-so about a woman, he might well put in low effort and try to quickly rattle off a hook-up on the first date. If however he's really keen on her, he'll put more effort into dates, texts and communication than went into the D-Day landings. He'll want her to be his girlfriend, he'll want to cuddle with her, he'll want to spend time with her, he'll want to introduce her to friends and family.

Ladies, I'm sorry.

If you're under the impression that men want access to casual sex, don't want relationships and don't want commitment, you're frequently finding yourself in the bottom-half of the conquests of a guy like me. You are just trying to 'date up', to 'box above your station' and 'overachieve'.

You've got every right to do it, you have every right to attempt what you like, but that's the truth.
