Is it safe to watch a movie with a small portion of nudity?

There’s a new movie that came last week called chainsaw man Reze arc. I’m 16 and my mom doesn’t want to take me to movie unless I feel like it’s a good decision. This animated movie has little non detailed skinny dipping scene and a part where a guy thinks about women in lingerie. My late Christian Dad didn’t mind me watching small scenes like this but my mom doesn’t think it’s holy. I was just seeing if anybody had any input if I should watch the movie or not.
