help needed

[Girl18]

Hello!
I've got one similar issue that's really connected with OCD.
So I was thinking "what if I am gay?"
My mind disproves that thought by thinking rationally.
But then my mind comes back and says "what if you like transsexual girls with men's parts?" and a wave of emotions like being turned on and enjoying it comes with it.
This thought really freaks me out, what if I secretly like that or smth?
I really hate these thoughts and don't want them, but they seem to turn me on.

Because you hate these thoughts proves that it is just OCD. You're constantly checking your feelings and thoughts for a response which is a compulsion. A few years ago I experienced something similar to what you are experiencing now. I let the thoughts be and eventually they disappeared.

This is definitely an ocd issue. No amount of reassurance can ever be enough. This is one question that cannot be answered with 100% guarantees,it is futile to try and only makes the ocd worse.
