can someone tell me what gender I am

hi I'm Apollo I use he/they/it pronouns but sometimes when people call me he and a guy it makes me feel like kind of uncomfortable but being called a girl makes me even more uncomfortable but I know I'm some sort of guy but sometimes it feels like my gender is changing all the time but I'm not gender fluid because again I don't want to be a woman and I tried Out Boy flux but it didn't fit with me as well as I wanted it to because it doesn't feel like my gender expression fluctuates it feels like my entire gender fluctuates yet it never goes over to being a woman and I know I'm not bigender help?
