Sexuality is partly a mood thing imo. Sounds like you're something along the lines of bi, but that's something only you can figure out. I tell people I'm a lot of things to get on/protect myself, but I lowkey know there isn't a hard limit for me on anything beyond things like feelings, compatibility, safety, or whatever else that could arise. Pansexual is probably the most accurate label, but it hasn't been practical..
Taking that stance just makes it simpler to go with the flow because you'll know your limits if you're in tune with yourself. You don't have to worry about making yourself fit some label either. If I think you're cute then that's that in my mind, and if I feel comfortable too I'll pursue it. A month ago I was mostly interested in girls, and this month I just want to cuddle a cuteboy, but if I was dating someone the changes in needs/desires wouldn't change who I love.
Taking shit like this too seriously just makes you lose opportunity to chaos.
