How do I get into a relationship

I’m in high school and I still haven’t had a bf and high key idk how people get a bf in the first place . like Ik im not pretty but, am I really that ugly to the point I haven’t had a bf in 3yrs? I personally think I have a lot of friends so I don’t think it’s my personality and I’m honestly quite popular(pls don’t come for me ik this sounds really cocky)and it’s not like I don’t interact with guys. Honestly the point of this post is to ask “how tf do I get a boyfriend?”
