THE self-proclaimed “King of Porn” has been arrested for allegedly forcing his underage girlfriend into making sex tapes.

Alex Marin, 37, who flaunts his luxury lifestyle and glam girlfriends online, was cuffed in the Mexican city of Jalisco this week.

The authorities claim the porn baron, pushing 40, lured a 16-year-old girl into a relationship with him and coerced her into making explicit videos.

Marin, real name Alejandro Marn Ramrez, was arrested by cops from the city’s state prosecutor on Wednesday and remains in custody.

Officials say he will be charged with human trafficking and sexual exploitation of a minor.

The governor of Jalisco, Pablo Lemus, said the case was being taken incredibly seriously.

He said: “The detainee, identified as Alejandro N., is now at the disposal of the judge to face the charges against him.

“In Jalisco, we take the protection of women and minors very seriously.”

Creepy-looking Marin is notorious in Mexico as the self-styled “King of Porn”.

He would post daily nauseating pics of himself cosying up with women in skimpy outfits.

The sex-mad influencer often boasted of having seven girlfriends – one for each day of the week.

He regularly featured in his home-made porn vids alongside the women.

Marin acted and directed in his own productions, which he usually shared through his company Solobellezas – meaning “only beauties”.

Shortly before his arrest he had posted pics from a party in Toluca, central Mexico, bragging about a new event.

The age of sexual consent in Jalisco is 16 – but Mexican federal law defines it as 18.

This is observed particularly when exploitation or abuse of power is involved.

That means any sexual activity involving an under-18 when these are at play can still result in prosecution.

If convicted, Marin could face between 10 and 25 years in jail.

Marin first hit headlines when, in his mid-twenties, he married a 17-year-old, Mia.

The pair were wedded for 12 years before announcing their split in February 2024.

He started off as a systems engineer but claims to have since grown his business into a global empire spanning Mexico, Spain, Colombia and Italy.

Marin was previously caught on camera brawling with a man on the street – as his girlfriend clung to him and begged him to stop.
