Every woman is different, and therefore their vaginal orgasm is different!
My ex-girlfriend’s vagina was able to accommodate a medium-sized penis, and my penis is also medium in size (16 cm / 5.5 inches), but of adequate thickness! My ex-girlfriend only had a uterine neck, and deep vaginal ( O spot ) and clit orgasm. My ex-girlfriend did not have a G point orgasm, and even when penetrating the vagina, it was only of medium size for a pleasant feeling! Clearly the uterine neck and deep vaginal orgasm dominated his vagina!
In addition to the right length and thickness of the penis, the psychological effects that promote and amplify a woman's orgasm must also be considered!
In the case of interracial sex, the anthropological characteristics of the particular breed are essential: pigmentation ( skin,hair,eye ), height, shoulder width, muscular structure, body fat percentage, hair and body hair structure, face structure ( wide,narrow,long,short ). For reasons that are understandable to caucasian and asian women who like interracial sex, these physical characteristics are important, just as it is essential for black women who like interracial sex that their sex partner has the right physical parameters! Sometimes I use a translator to read african american ladies romantic forums, and many longed for a caucasian man outright or were basically open to a romantic relationship with any kind of man . Many of them highlighted the different breed characteristics, which for them is considered an aphrodisiac in the erotic / sexual field!
This is also the case for many white ladies, for whom the possibility of interracial sex is highly attractive , which is why they can experience forms of vaginal orgasm that they could not experience with a white man!
