Porn sex use actors and rotates around money. Real sex takes time; relationships, good with dating/hook ups.
the reason why actual sex is better than PMO, your brain activities while PMO are similar to the ones doing drugs. During real sex, you have different brain activities that don´t harm your brain, unless you do it multiple times a day.
Real sex doesn't have (usually) have heavy make up, start stops, 40 minute marathons, bright hot studio lights, camera and a sound guy... and other people. There isn't a emphasis on spread genitals to capture it on camera or providing louder than usual noises. Of course there are exceptions. I assume you are a virgin? When you undoubtedly have sex you will know how different it is. Its messy, spontaneous, dirty, sleepy both in the morning or night. Sometimes your breath smells, sometimes its long, sometimes its quick. Its also start, stop. Positions are limited most of the time. there is also giggling. It also has a lot of emotion depending on the relationship you are having with the girl. hope this helps.
I don't know what kind of kinky weird shit you do but the sex i have is definitely less dirty than porn hahahaha Totally relate to the being sleepy part though.
Dirty as in messy. Sometimes if you are comfortable you can also do it with a partner on her period. Its an exchange of bodily fluids. Which is why you always need a shower after Sex feels dirty and it is dirty. On a porn set it usually looks very clean and pristine.
