Use lubricating fluid to mean "no"?
The amount of sexual organ secretion is not directly related to sexual performance! The amount of secretions varies from person to person, and the body's response does not necessarily directly represent sexual arousal.
That's why it happens: I want to have sex when I'm sexually excited, but my body isn't wet; or when I touch the head of my penis, there's a transparent discharge, but there's no sexual fantasy in my mind at all. So it's not about you/partner, it's about your body~
If you want to try it out, you can buy Fine Size Water-Based Lubricant, or buy Pack for your side!
