What is does precum stain?

Precum, also known as pre-ejaculate or pre-seminal fluid, can potentially cause stains on clothing or bedding. This fluid is secreted by the Cowper's gland during sexual arousal and can contain small amounts of semen, which may contain proteins that can leave a stain. However, the likelihood of precum staining depends on the fabric and the amount of fluid present. Clothing made of absorbent materials like cotton or silk may be more susceptible to precum stains compared to synthetic materials. Proper washing and stain removal techniques can usually help remove precum stains from clothing and bedding.
