This issue recently came to my attention (its not a new one, but it has happened to resurface) and it completely bothered me that the (cis) male sexual partner involved was so ignorant.
Most women do not reach orgasm solely through penetration. This article on Women’s Health Mag claims that only 25% of women having penis/vagina intercourse are having orgasms (according to most major surveys, this 25% is most likely an average). The rest of us, however, cannot achieve the “big O” solely through penetration - we need extra stimulation.
So when someone pops off and tells you that it is “abnormal” that you didn’t orgasm when all they did was fuck you (via penetration only), please remember that it is a statistical improbability that they have been so lucky that all their previous (cis) female sexual partners were able to attain orgasm through penetration alone.
