I was talking to this girl and she was talking about how she took some guys virginity and I got a groinal and it’s giving me intrusive thoughts about how I’m aroused by the fact she was talking about a guy... 😞😞😞

Did you ever consider the fact that talking about anything 'sexual' in nature could cause a physiological response? Alongside this, your brain is scanning for a physical reaction, because of your OCD. It's like focusing all of your thought on your little toe.
