David sings a lot about girls etc. but it seems like he don't like to flirt with girls/kiss and stuff. What do tu think? Why is that?

I think its bcuz hes too innocent, shy and cute to do stuff like that.

I amor HIM más IF HE'S GAY!

Because he's waiting for someone special that he has'nt found yet and that person is me, lol.
I agree with imortalsoul17.

i think he sings about girls to mostrar he likes them, but he dose not flrit o kiss them because he is mostrando respect

Because he is a good man...
He don't do stuff like that because he have a good attitude and he respect woman very well...

Remember his song, " my kind of perfect"?
I think he's answered this pregunta himself. He's looking for that one person who can truly make him happy and I agree with what he's doing, not rushing into things.

His die-hard fans like myself amor him just the way he is.
