iT does not matter how big it is its how you work it and wherre if there is foreplay fisrt and oral second a woman has to be touched on the clit in such a manner the it makes her cum first ,thats just getting wet in the vagina fir the penis to enter,an orgasm is after you have been having intercourse for several times and the g spot starts to get realy touch it will even jerk a little the clt and the g spot the vagina will seem to get real tight and it will seem to feel like you have to pee than when the muscles contract on the penis the orgasm will explode and you will see stars or even lights blinking and it will gush like never before ,but you have total completeness in and believe in your partner no matter what he does ,I had a girl friend in fact 2 which never had a orgasm they came yes but the orgasm was left behind until we met it also takes time for an orgasm at times no woman is the same if you  would not mind I could tutor you on this until you felt complete.twe
