every time my girlfriend gets close to having an orgasim she starts to laugh hysterically, she likes it but i guess she gets too sensitive when she gets so close. whats up with that and what can we do about it?

Not sure, and not much.

man, sometimes i get that way with my girlfriend. it's weird, it's like too much stimulation. i know that sounds dumb, but sometimes it just basically tickles. i suggest working around her "hot spot" since that's the most sensitive spot, and test her out to see if and when she's ready for more. i don't know if this helps.

Attitude changes with altitude!! Could be that you are just "working" too high!! Lots of girls are ticklish when you poke them in their tummies. Try moving your action down a little bit, and see if her attitude changes!! (hee hee)!! Love, Venus.
