He’s not only a fan — he’s a follower.

Left-wing state Sen. Gustavo Rivera follows dozens of salacious accounts on TikTok, including at least 36 who also maintain OnlyFans accounts, a review by The Post shows.

They include brunette influencer Jesse Switch, who recently posted a video demonstrating various ways to make a distinctive sound with her money-maker.

“Have you ever wanted to learn how to make it clap?” she asked.

Other TikTokers tailed by the Bronx lawmaker include Heidi Lavon — who is on OnlyFans as “Viral Cosplayer,” marching around in tight leather ensembles, holding whips.

The lawmaker follows at least two little people who have porn accounts, including one where British creator Peta warns her TikTok followers that her thighs are “skull crushers.”

Playboy star Jenny Locke had this observation for Rivera, and the rest of her followers: “You’re cranky because you need to get laid.”

Critics weren’t surprised by the TikTok roster followed by the Albany Dem, who has previously proclaimed his support of prostitution and has co-sponsored legislation to decriminalize it.

“It’s not inconsistent with Democrats’ policy of sexualizing our culture,” said a GOP state lawmaker “This is their agenda, from legalizing prostitution to normalizing public displays of lewd behavior.”

Rivera, 47, serves as Chairman of the Senate’s Committee on Health and is unmarried.

His personal TikTok account has posted no videos.

It is followed by many of his extreme left-wing colleagues, including Socialists Sen. Julia Salazar and Sen. Jabari Brisport.

Rivera declined to comment.
