Boys, are we 13? Sharing masturbation technique? It's your own dick, how to make it feel good, I don't think we need to share right? We should have "graduated" by now? Unless you are really 13 years old?
I might understand if you had done with hot girls before and don't want to lower your standard. But if you are cherryboy and could have sex (even dry sex) with some ugly girls, dammit go for it. TURN OFF THE LIGHT so you don't have to see her ( tell her it's romantic). Or if she's really so unattractive, at least use her mouth to "masturbate" into.
You know I have extremely high standard for JAV actress, but that's because it costs nothing to pick the best AV to download (or even buy). But real sex, GODS I can't understand it. Piston-pumping a vagina, grabbing tits (even not the perfect pair) is what it's about.
One thing is ugly and fat girls can be excellent fuckers (they tend to pay more attention than pretty girls to learning good techniques), just turn off the light and it may prove to be magic; even not magic is better than self-service.
About sensitivity: For me a quickie is anything under 15 minutes (only if I'm super tired but need to relieve before sleep or in a real hurry to go to work but can't zip up my pants due to the huge buldge). If a quickie doesn't last long enough, what almost always happens is that I wake up an hour or two later and need sex again, so I've pretty much stop doing quickie. Rather I'd just make her suck my cock for a few minutes and NOT cum, or she might hold my erect cock in her hand while we both fall asleep. Until we have the free time for proper sex. Most of the time, that means at least 30-45 minutes. If we were watching porn, often she would lick and suck my cock (very slowly) while we watch a scene or two together.
Once in a while if we both have free time and feeling really horny, we do this super long, broken up session. I would feel up her tits off and on and she would suck my cock off and on, we might interrupt with eating some food, drinking some wine, watching porn or regular tv, even sometimes she would be watching regular TV while I separately browse/download/watch AV on the PC and I'd randomly molest her sexually or vice versa. Once I convince her to let me fuck her in the pussy everytime her show goes to commercial break. Or even we might interrupt ourselves and separately do some totally non-sex thing, like play games on our smart phone. Sometimes we might be doing vaginal sex and than we want to up the game so we get into the shower to do some deep cleaning. But the cool air will of course makes me lose my erection and we have to restart the foreplay. So sometimes the whole session last more than two hours before we get the "up game" in gear: which is ANAL SEX. And because how the anus feel different, I can hold off my own climax and I can keep piston-pumping for quite a long time. If I get tired, (especially if she already climaxed) I would take the necessary rest while holding still my erection inside her ass, before resuming the piston-pumping again.
We both love slow sex and I especially enjoy the process rather than the end-game. Strangely I love anal sex, but often the ejaculation itself isn't the best, as if after holding off climax for too long, the climaxing doesn't work quite right. And a few hours later, I need to masturbate to get the rest of the climax (and ejaculation) done with.
