I am paranoid I am now becoming lesbian or bi. I have never been interested in girls, and have always known I want to meet a guy and fall in love. I've had crushes on men my whole life and never doubted my sexuality. For months I've had obsessive thoughts where my mind comes up with all the reasons I've been in denial my whole life or didn't know I was gay. I can't get lesbian thoughts out of my mind, and they cause me so much pain in stress. I also need to check myself for arousal when I see girls on social media. I (only as of this week) get a nervous feeling in my chest when I see girls or their bodies. This feeling has never happened before. I'm scared now my whole future will be ruined, I seriously don't want to be with girls but my mind tells me I'm in denial when I know I'm not. I go to sleep scared I'll have a dream about a girl, only once did I have a lesbian dream and it causes me so much stress. I know I like guys, I flirt with them, I get crushes on them, etc.
