at what angle exactly are you supposed to push during sex ? assume missionary position and suppose your dick is pointed 45 degrees below the horizontal, at this point you have three options 1)push at exactly 45 degrees 2)push below 3)push above

obviously 1) isnt correct but i was trying 2) at first and It felt somewhat good but I wasnt actually penetrating her at which point she told me to push above but all that was happening was it was bouncing off which brings the question, are you supposed to place your penis at such an angle where it bounces off some arbituary spot near the opening and into the vagina as you push past the arbituary spot which creates a paraboloid trajectory into the hole ?
