I concur, when you're young, you are just happy to be inside a pussy......hence why most younger guys are terrible lovers......
I also would prefer no sex to bad sex......it isn't that i only have so many shots left in the chamber, but like i say a lot....if you only ever have crappy hamburgers you think it's prime rib....that is until you have prime rib. Once you've had prime rib, McDonald's just doesn't cut it anymore......
Now onto defining bad sex......even quickies can be good....in some situations, it's better than a marathon......
To me, bad sex is where you just don't work together. It could be because it's like throwing a hot dog down a hallway, or your peepees just don't line up...or she's just not into it, or you're just not into her. That's why some comment on what i find attractive in the ssg, ghm and dh threads.....so, for me, i have to be physically attracted to her......then i have to respect her. She has to have some sort of mind, have something upstairs....one of the biggest turn offs for me is when a woman says something so ignorant, or inane that i just cringe......they also have to be able to communicate without any hangups. for eg: i dated this hottie, really insecure for some reason, but all of a sudden she'd just shut up....and kind of pout. After literally hours of prying i find out she's imagined something that i supposedly did wrong...i stuck with her because 1) sex was fricken amazing and 2) in many other respects everything was good and she wasn't a dummy.
Anyhow......
