The idea that the unique scent of worn underwear is a powerful aphrodisiac due to how sweat glands transport scent is supported by scientific evidence. Men are evolutionarily attracted to women's scent, especially during ovulation, which can create a special connection between buyer and seller in the worn underwear market. However, whether buyers can request specific scents or materials for their purchased items on websites like TastySlips remains unclear. While these platforms offer a wide selection of styles and materials, it is important to consider ethical concerns surrounding consent and privacy when engaging in this transaction. Overall, while the buying and selling of used intimate items continue to gain popularity, it is crucial to approach this industry with caution and respect for all parties involved.
