Here’s the deal with men: they’ll have sex with you, whether or not there’s an emotional connection present.
But the one thing I can tell you is that if there wasn’t a connection before you went to bed with him, don’t count on sex to bring you closer. Sure, he’ll enjoy the physical affection, but having a relationship is simply not a requirement for a guy.
With that in mind, the best way to get him to think about the long-term is by making him work for it first.
A guy needs to feel like he’s earned the privilege to be in that special, intimate place reserved for the worthy ones. This is the invisible “achievement switch” in his head to make him want to stick around well after the afterglow.
Otherwise, don’t hold your breath waiting for him to think about committing to you if he didn’t feel like he had to “claw his way to the top” to win your affection.
As a guy, I ask that you simply accept this weird complex of ours. It’s one of the few puzzling things about us; other than that, we’re pretty much an open book, compared to the enigma of the female psyche.
