How do guys lubricste?

Guys typically lubricate by applying a personal lubricant, which can be water-based, silicone-based, or oil-based, to reduce friction during sexual activity or masturbation. They might also use saliva as a natural lubricant. It's important to choose the right type of lubricant based on the activity and any materials involved, such as condoms. Always check for Allergies and ensure compatibility with any products being used.
