Pregnancy needn't be the expected result of intercourse, and in most instances it isn't. I don't have that philosophy, pregnancy should always be the expected outcome if you are not protecting yourself from it. Therefore no suprise.
I never dictate to anyone what they should do. I state my opinion and apply it to myself. I can't control what anyone does, nor will I condone it and pat her on the back and say 'good job Chrissy'
