The Dry humping is see as a form of intimacy (think like outercourse etc). This technique provides a different kind of orgasm compared to hand/oral/intercourse.
From what I have figured out is men actually have three zones for pleasure. The head which actually most western civilizations damage with Circumcision, the base of the penis in the general area where the prostate can be effected by the bladder, and the prostate (p-spot).
P-spot orgasms are supposedly give similar orgasms to what women have with full body, while the base of the penis is a combination of the head and the prostate version. The pressures involved have an elongated orgasm, where intercourse and hand (and similar to oral my guess [ I don’t know the oral aspect due to trauma from abuse]) are more radically explosive and quick and then die off ….
The article is right it does put men into a position of delayed ejaculation which may put the female partner off because they presume the man doesn’t love or like them due to no emission.
Hope this helps ….
