Impact of tiktok etc on relationships

I'm interested in other people's thoughts about the information and content that is shown on social media platforms and how it effects relationships. For example, I'm not a tiktok user but my partner does have it on his phone. He is interested in many topics like politics, cooking, pranks and sport and apparently he gets lots of entertainment on it. However, I have also seen loads of females showing their bums and boobs popping up on his feed and when I'm in his company he scrolls past pretty quickly! I get to thinking what is that all about and why does it create some concern and anxiety in me? Before technology any image of titillation men felt they needed was in the form of a magazine which had to paid for and viewed privately. Girlfriend/wife was oblivious and not at all threatened as there was no knowledge of it. Now it is freely available and in one's face 24/7 together with an opportunity to connect! I just feel that watchers who do not want to follow these girls are still being force fed these videos. It gives partners no reassurance or confidence, infact it creates anxiety everytime the app is opened. What are your feelings on this?
