Try to be cautious around terms like "proof". OCD wants you to be sure, one way or the other, 100%. Nothing in life is this certain, including most definitely our sexual orientations, how we feel in relationship, our attraction to others. Nothing can be 100%. Sometimes people can get upset when things DONT cause them anxiety, and then they get anxious about that becuase they're worried - what does that mean about me?! Try to just allow that question to be there. The question "why is this thought not causing me anxiety?" is the intrusive thought - you can't help that. Trying to ruminate, check yourself, or review the situation are all compulsions - and those things you can help/you are in control of.
