19 y/o need help

So, I’m 19 and I lost my virginity earlier this month to a guy I’ve been dating and I really like him, but for some reason, I can’t get that wet or aroused...but I get really wet and aroused when I watch porn. I decided to stop watching a long time ago, but I don’t know why I can’t get aroused with him.

We do foreplay long enough, but I just don’t know :(
