Women enjoy giving more than taking.
We love making you feel good, we really do. But automatically assuming that our feminine side means we're not into sex for our own pleasure is incorrect.
We want to climax. We're not preoccupied with achieving orgasm from your penis alone. Your mouth, fingers, and even a vibrator will do just fine. But if you climax, we want to climax too! Don't leave us out of the fun because you assume we're above getting off. News flash: We're totally not.
And yes, sometimes we'd like to be the selfish ones and get some oral sex before going to sleep without reciprocating. Guys shouldn't be the only ones to get a no-backsies pleasure session. Share the wealth!
