Masturbation can also act as training to maintain an erection and avoid premature ejaculation. Learning how your body reacts to stimulation, knowing when you are about to orgasm, then holding off, can make you last longer with women. But you must practice.

I agree with what you say. But it's more than just that. Porn also teaches you a little how to take a hot lady's butt.
Recent research in sports (Golf) has found that mentally rehearsing some act makes you better at performing it. An author of this study says, "The findings suggest that simply viewing a video of another performing an action may bolster one's ability to imagine and subsequently perform that action."

The only thing about porn-training is that it's incomplete for real sex with real women. Because in porn, the lady prepares herself and she is ready, when studs start taking her. But in real life, you usually need to foreplay the lady to make her ready. If you try to take her like a porn-stud, when she isn't ready. Then it simply won't work. Because the sex will be uncomfortable or even painful for the woman, and she will stop you.
I think there is something to be said for more realistic sex-action in porn, where guys truly and fully foreplay their hot chick, before they take her with their dick. Because watching this would make porn-fans better studs in real life with real women.
