From PostSecret, the above.
Understand, when a woman doesn't orgasm when fucking you, it's not your fault.
A girl's orgasm is mostly in her mind: if she can orgasm with some random drunk stranger that she picked up in a bar, she can orgasm for you.
She just chooses not to.
Two things to do:
1/ be offended and find another girl (because it is offensive to be lied to sexually, so intimately)
2/ stop worrying about her orgasms and use her as the cum-bucket that she is, focusing on enjoying YOUR orgasm instead, while at the same time looking for her replacement
Welcome to the poison that is modern relationships.
