No of course not, I mean only that once I get started, I don't rush to finish. I enjoy feeling horny, I don't mind interrupting the sex, take a break, eat some fruit or drink something. Maybe I would lose my erection, (if we take a shower to prepare for anal sex, I always lose my erection stepping out of the hot shower into cold air. Sometimes my partner want to start a conversation, which is not what I want, but fine I don't mind interruption. Maybe if it's a serious conversation, I just have to pull out (I hate to admit it but I don't have enough blood to keep up the little brother and think seriously at the same time). No matter, after the interrupt we will get back into the action.
My own way is: being horny, having a erection itself is great pleasure, the process of fucking, every stroke is pleasure. But for a lot of boys the climax/ejaculation is the pleasure, so the strokes (masturbation or fucking) are efforts to reach climax. Actually for me masturbation and sex are hugely different. Masturbation often last under 10 minutes, pop on a JAV, jumps to each parts that I find stimulating, stripping the girl, tits-play, blowjob, fucking... with my left hand I use the mouse, my right hand stroking, a scene is compressed down to 3 minutes. Boom I cum. I don't think I can live without masturbation, but sex is much much better.
I know I can't be a porn star, at least not without taking a pill (have never tried). If I'm piston-pumping as hard as those porn scene, I won't last 5 minutes. Perhaps I could be a male prostitute, maybe I could please many women. But to perform sex for the camera is something different.
