Unless your girl has the mighty thews of the bicyclist in The Triplets of Bellville, that porno style squat bouncing gets old fast. You try it. Not fun. Plus, minimal clit stimulation. So why bother, really? The whole point of having her on top is so she can get herself off any way she wants - i.e. all about using your dick to work her clit. She can't even get the good visual you've got either. And if one's legs do give out, I've always thought there was a high danger of breaking someone's dick, and no one wants to take that visit to the ER. You can also prop yourself up so you are closer to sitting than lying down, and she can use her arms to help, or you can use yours to help (maybe a headboard assist? - sex trapeze? - bungee jumping apparatus? Dairy farmer's milking stool with a hole cut in it (the spring loaded type)?). If you are really attached to the porn bounce, develop your arms and upper body to the point where you can lift her up and down like that. Good luck. I really don't think most women actually just post up and down vertically for long periods of time. It's boring and it's at best tiring. Leaning forward or back is easier, kneeling is better, and grinding is a lot more fun. You do nothing but deep squat bouncing and your legs would get all crampy, you'd gradually get less and less concerned about dick damage, and a trip to the ER would seem a welcome respite from the charlie horses forming in your calves. Perhaps they would have pain killers there, you'd think through gritted teeth, and if this bastards dick snaps off when I collapse in agony, I'll never have to do this for 45 minutes again. Purely hypothetical situation, of course.

Do people think this is Porn Sex striking again? People don't really have sex like in pornos, that's display sex. Usually guys are the victims of this and you have to educate the young ones out of it. Bad or good that girls are imprinting on it too?

hahahahahahah

Damn,.... you were right!

Er... Not to pry, but does "you were right" mean "We changed it up to something more realistic and it was great" or "Oh god I snapped my dongle WHY DIDN'T I LISTEN?!"

Yes, the former... less bouncing, more scooting...
