Lol ok dude.
Because women dont lie to men about sex or fake orgasms right? Theres a big reason why surveys and studies on female orgasm differ with what men believe women are telling them. And its because women will spare a lot of guys ego when it comes to the reality of if she had an orgasm or not.
Any data you find on female orgasm will tell you that at most, 1/3 of women can orgasm from straight up vaginal sex. The rest need ****oral stimulation in order to climax. So believe whatever you wish, Im just telling you what Ive gathered from years of reading up on human sexuality and talking to different kinds of people.
Women (and people in general) are more likely to be dishonest with the man they are sleeping with vs being dishonest to the doctor or sexologist asking them questions. Especially considering how much pressure there is on women to orgasm and how much pressure there is on men to make a women orgasm. Its no secret its a huge ego thing for both men and women.
