I know exactly how you feel! This is me totally. I'm a female, girly yet a big tomboy myself. Never questioned myself til about a month ago , bam stupid thoughts came up and I've also had bad ocd in my childhood. You're not alone girl! It's the ocd. You're not gay, the orientation is already hard lined into you, it's your brain hats going haywire. If you need I talk, PM me. But don't freak out. Let the thoughts come thru, make their place. Don't fight em. Remember who you truly are, who you were before all this bullsh*t. You're not alone, trust me.
