Is it normal to not get wet ?

Hey everyone :

Im 18 My story is that im a very horny person.I have a habit with watching porn. And i've been masterbating ever since i was 11 or 12 maybe even younger !

And I seem to not wet myself anymore! my part down there is darking up and its just ugh ! Is this normal?! I dont even cum ... and if i do its like the next day ! I'll have it.. When its all dried up and looking weird sometimes its like dried glue. What do u think about this?
