My girlfriend has a lot of anime guy pfps?

Ik it might be a stupid question, but my girlfriend has a lot of guy anime pfp in her phone and it's making me a bit worried, I mean, she is a bit uh over to it if it makes any sense, what should I do about it? And all guys in the pfp have muscles or so, it's making me feel that am not enough for her somehow

An update i forgot to mention, she is a bit over simp for them, like we can sometimes have fights over it even if I make a small joke over them (the characters she have in her phone) she is a good person but I don't know it's like if a good looking guy then me comes to her she is ready to invite him to her bed that's how I feel most of the times now due to her behaviour..
