Callum, I admire your courage for telling your mom about it. I'd never do that.
Anyway, with me, my HOCD is like an on/off switch. Sometimes during the day, it switches on, and I'm getting all anxious and worrying and the repetitive thoughts etc. Then when it's switched off, I'm my normal self, and can happily enjoy girls.
It's a pain, but yeah. I know I have other obsessions, a big one with me is when someone gets sick and I am terrible. I will lock myself in the room, only come out with a face mask, wash my hands about 20 times, make sure I don't touch my face or anything. Haha, it's pretty bad.
