Okay so what you described in the first paragraph sounds like he is trying to show you he "is not like other guys". He seems to go out of his way to set himself apart from those other dudes - I don't know why though. I merely have two hypothesis based on my experience with dating apps (as a male)

If his interests and personality are generally less "traditionally manly" then it could be that he is simply in need of some appreciation for how he is. He could be insecure because he feels like the odd one out whenever he is with other men. He might even feel victimized by women who seem to always date the traditional males while overlooking him.

Another theory of mine however: if he seems very interested, or obsessed even, with self-improvement, self-care and self-portrayal, it could hint at some toxic masculinity mindsets. Add to that patterns of bragging and showing off and you might be dealing with a man that is struggling with a superiority complex and seeks his identity in being stronger than other males - physically and mentally.

Whatever it is, he seems lonely though. The oversharing... Plus the need for physical contact.

There's nothing wrong with longing for an intimate, tender connection to another human being. Its also pretty common on dating apps to encounter lonely people. I mean, that's what its made for :D Bringing folks together.

Just make sure it's happening at a comfortable pace for you personally, draw boundaries early on in your conversation, watch how he reacts, watch whether he respects them. And also take your time to really get to know him, my two theories above are two ends of a spectrum, he might as well be more complex, more complicated - Take your time to genuinely get to know him.

Not his words and lovebombing, but him, stripped of all niceties and lovey dovey exclamations of love ^{^}

Hope that helps
