The partnership is the largest in KSEX's history. Rude boasts more than 1.2 million members.
"The addition of the KSEX lineup provides our members with fun and diverse entertainment, providing them with a behind-the-scenes look into the adult industry," said Chandie Foster, marketing manager of Rude.
KSEX Vice President Joe Brandi said he also looks forward to the partnership.
"Working with a company like Rude is very exciting indeed," he said. "Rude.com has a vast audience with over 4.7 million page views a day and a great amount of unique visitors. Not only is this going to greatly increase the viewership of KSEX, but also gain a ton of exposure for our sponsors and advertisers.
"This is going to take KSEX to the net level quickly. We look forward to a long and successful relationship."
