Being sexually excited by a partner wearing clothes rather than being naked.
People who enjoy this type of sexual arousal are known as “clothing fetishists.”
Clothing fetishism is one of the most popular and widely accepted forms of sexual expression today, and many people find it an exciting way to express their desire. The endytophilist is more turned on by his partner clothed than naked. Often, the fetishist would also prefer to wear clothes (than to be naked).
There are many websites on the internet with so-called "no-nude" porn. It is often seen in connection with "dry-humping", where the partners rub themselves and their genitals against each other while wearing clothes.
