Urolagnia is a fetish that focuses on urination during sex. This can include, but is not limited to, peeing on someone during sex or watching someone pee. This may also be referred to as "golden showers." R. Kelly was infamously linked to this fetish back in 2002.
Sweating during sex is a normal occurrence. During sex, a person's heart rate and metabolism increase and accelerate, which may lead to sweating. Sweat is also believed to release pheromones, the scent of sexual attraction. Body odors, like sweat, have been linked to playing a big part in sexual attraction and as a natural aphrodisiac.
