Dry sex is the sexual practice of having sexual intercourse with a woman without vaginal lubrication. 

Which means that; dry sex is the act of having sex when the woman’s vagina is dry, (having sex before when the woman’s vagina is lacking the lubricant fluid).

When a woman is sexually aroused, the vagina produces a lubricant fluid which helps the male’s penis to glide smoothly into the vagina during the act of having sex. 

Vaginal dryness is the condition in which this lubrication is insufficient or lacking, sometimes artificial lubricants are used to make the woman’s vagina dry.

Dry sex can be painful for men and women due to the virginal dryness.

Some men who insist on having dry sex regard vaginal dryness to be a state which increases sexual pleasure, and vaginal tightness. 

Rapists, pedophiles, and dagerring dancers always end up having dry sex due to the violence (the beating, insulting, and the physical abuse) associated with the activity of sexual intercourse.
