Husband (30M)watches teen porn.

For the context, we are both in our early 30s and I’m not against him watching porn, what bothering me was I found out he was searching “Greek teen porn” .. the thing is we just hired a Greek girl at work who just turned 19, is he actively sexualising her?should I be concerned?or I’m thinking too much??? Do all men likes to watch teen porn as they get older???
