intrusive thoughts about my sexuality

hi does anyone else have this intrusive thoughts about lying about their sexual orientation? In the past I suffered from various intrusive thought about anything that was dear or triggering to me and I know these thoughts is not who I am. But what if I’m a big fat liar and I want to claim the title of someone I’m not? I’m so scared because I love women and I would like to spend rest of my life with another woman. Probably I will have ons next week, do you think it’s sufficient proof I like woman if I will enjoy having sex with one? Or is it not enough?

I have trauma including men, I tried to date them but it never worked out. I’m scared to death the only reason I fantasize about women is because I can’t be with a man.
