In Africa, women use leaves, dung, and hyena urine to dry that vagina up. Less wet, less lube, more friction.

They also use sponges, detergents and some traditional herb concoctions or so I've heard to dry out vaginal secretions, in order to have sex with a lot of friction, apparently the vagina "clings" to the penis during dry sex, this also leads to a lot of abrasions and trauma to that vaginal canal, resulting in bleeding which is the perfect environment for transmission of HIV.

Apparently it feels better but it causes lots of tears and breaks in skin which leads to higher rates of HIV infection in Africa. If she’s not aroused she could clench in fear or be dry, causing extra friction and painful tightness, she could also feel looser and have more friction because the vagina and vulva engorge the same way the penis does when aroused, the inner wall should be really squishy and plush and hug closely to even a pinky finger if she’s fully engorged. But if she's not fearfully tightening it can be loose and not hug your dick. This leads to more tearing and bleeding of the mucosa, resulting in a path for the virus to enter the body.

Negroes in the states don't care for lube either, which contributes somewhat to the prevalence of AIDS among women (including coalburners) in the US.

Doesn't feel enough like rape if the chick is wet, I guess. Regardless, negroes most likely have no idea how to wash their dicks after sex, or at all, and having that AIDS ridden sex juice marinating on their mucosal membranes would obviously be a bad thing. And AIDS for all, YOLO!
