Intrusive thoughts about sexuality

Hi, so I don’t want to offend anyone part of the LGBTQ community but I’m just having these unwanted thoughts. So I’m having heavy intrusive thoughts about my sexuality, I’m getting so much anxiety I might be bi. I don’t want to be bi. I want to be straight. So I have never wanted to do things with girls but my thoughts tell me otherwise so now I’m worried. Has anyone who is straight also ever get anxiety from being bi or lesbian or something? Please help thank you!
