I wouldn't panic, if I were you. You're still a virgin, so you don't know that the two aren't really comparable (actual sex versus porn). Plus, I'm sure it's difficult to perceive how awesome something might be, watching someone else do it, when you don't know what it feels like.
Dude, I can't even take porn seriously. If I see two dudes going double-penetration on some chick, with an extreme close-up of their balls slappin' together, I find it difficult to contain laughter. When I see porn, I have to make fun of it (What the hell is with dudes smacking their cock multiple times on a woman's face, or ass after pulling out???). Also, the stuff they do in porn isn't really reflective of actual sex. A lot of what they do is for cinematography and appearance, not for actually getting off, like two people having sex would be doing (unless the scene's supposed to show that.).
