When a girl is so hot that you spend most of your sexual thoughts focused on her, leading to a massive erection that seems to almost never go away, she has given you the eternal boner.
Guy 1: "Dude, I can't stop thinking about Anna. She's so hot, bro."
Guy 2: "That's because she gives you the eternal boner, man."
Guy 1: "Word."

When you can't stop getting a rock hard erection every day thus only being tamed or cured by jacking off

A boner men get when they’re around the girl that they see as the hottest girl in their opinions. Eternal boners can happen from a guy looking at a super hot nude girl on porn, seeing a naked hot in person when they’re about to have sex with them, or seeing their crush naked whatever if it’s in porn or real life.
Me: Man, I cannot stop thinking about Matilde. Every time I see her naked pictures and videos from her Onlyfans, I feel like I get an eternal boner. If I see her naked in person, I’d really have an eternal boner.
Person: Dude, you’re obsessed with her. You wouldn’t last one second having sex with her.
Me: Yes, but I’d still have a huge boner after cumming. I bet I could cum multiple times.
Person: Yeah, right.
