A hookup is just a relationship, HOPE. It could be a short-term relationship, but it is a relationship irrespective.
And, yes, a short-term hookup can develop into a long-lasting relationship, HOPE, although not if you are dealing with your hookups like shit (simply because they're just hookups!) rather than if you should be ready to allow the individuals you hook up with treat you would like shit (as you're merely a hookup). Treat your hookups like individuals you could in fact see again—like people with individual feelings, perhaps not simply individual holes and/or poles—and you may in fact see them once again.
You could also end up in a long-term relationship.
Now, sometimes people hook up with strangers correctly simply because they wanna have sexual intercourse with some one they don't really understand plus don't expect you'll see once again. And that is not at all times an idea that is bad making love with an individual who that you don't be prepared to see again can be extremely liberating. A woman who can not let herself opt for a man she is dating—maybe she fears being slut- or nympho-shamed with a boyfriend—will grind the cock off a hookup. And it will be much easier to ask some body that you don't expect you'll see once again to accomplish something kinky.
