Porn is fantasy, plain and simple. The performers aren't simply messing around and having a good time, they are doing what looks appeal and faking pleasure. I'd encourage you to read an article of what it is like for the perspective of porn stars. I've read descriptions that describe it as awkward, doing unnatural things naked in a room full of people behind the camera. It's shot and edited to make it look fun and natural, but it's anything but.
The first time I had real sex, I had high expectations from porn. Thankfully, I liked the person I was with, so the emotional intimacy was great, but the kissing was messy, the blow job felt like nothing compared to my hand (still working on death grip), and once I got the condom on I lost my erection and couldn't finish. I was expecting it to be effortless and intensely pleasurable, and because of my porn habit, it was just awkward and embarrassing.
After some getting used to it, I ended up having good sex. It was still messy and awkward. Neither of us had perfect bodies. Getting the condom was still an interruption. It smelled like latex and lube. We got tired and out of breath from seemingly mundane positions. We had to start and stop a few times. We even laughed about how awkward things were. However, once we got into the zone and had an emotional connection, it was way better than anything porn ever offered me.
If you expect sex to be like porn, you're not going to enjoy sex. Porn is to sex as romance movies are to love. It skips over anything that's not beautiful, but in that way, it kind of misses the point.
