Starting Y12 as a girl in a primarily boys 6th form?

Hi, I've seen variations of what I'm asking but I didn't get enough info from it. I fell in love w the academic support from an all boys school, but I've grown up in an all girls and don't know any guys (I don't have many friends of any gender tbh, I stick to 2-3). My biggest concern is how to socially adjust. I'm not looking for finding a bf, which I know is the reason some stupid classmates in my school want to move 6th forms for. Also there is inevitably drama that gets shared to me of this school, such as some boys ranking girls and objectifying them or sexually harassing them.

I just want to be able to make a friend or two and focus on my a levels and my future career. So I can better understand what this environment may be like, I'd appreciate if people could share their experiences regardless of their gender.

Did you ever feel like you weren't safe? Were you able to adjust quickly? Do you think I could be potentially harassed if I go there? I just want to focus on my a-levels... sorry if it sounds like I'm overthinking, but none of my friends are even considering going there.
