During the female orgasm, endorphines are released, which are powerful painkillers. A lovemaking session can release the tension that restricts blood vessels in the brain. So headaches are in fact a bad excuse not to have sex.
“The truly submissive girl doesn’t hide. This is who I am, she says; take me. It’s not only her body which she makes available. She invites total intimacy. And is not that what we all seek, even if we so often refuse it? In doing so, she inevitably makes herself vulnerable. In letting you reach right inside her, into the quivering core of her being, she runs the risk of being harmed. You can do damage if you aren’t careful. But she trusts you enough to run the risk.” —Discerning Dom (via hisdarlinggirl) (via ravenskink, hisdarlinggirl-v1) (via simply-susan)
