I'm not sure of my Sexuality

So I've realized until now that as a boy, I've been attracted to strong-willed, tomboyish girls and I only view other girls without those characteristics as friends. Later I found out that one of the girls I've been attracted to had gotten themselves a girlfriend. I've been thinking if I'm really attracted to girls or just using these characteristics as an excuse and actually attracted to boys. Because one time I found my male classmate attractive that I just want to get close to him but his personality turned me off. I am a also a little effeminate so I do get along with girls and I can be a gentleman and show courtesy to girls as well, but what I also want is to be shown courtesy like to other girls, I wanted to be the one protected and cared for (a treatment which mostly only girls get). So I wonder: What exactly is my sexuality?
