Thank you all for your thoughtful comments.. it really helps knowing you guys have found a solution.

My gf does suspect I have a fetish, but I've never told her. She can tell that I have a real thing for her hair, but I never comb it or anything.. just sometimes play with it, and sneakily get a "hairjob" sometimes ; )

I think it would be wise for me to tell her, especially if I get caught again. I don't want her to think I'm looking for another girl. I do need to be more careful anyway. Would be amazing to get to the stage where my gf is pointing them out.. she's already pointing out nice bums (which she seems to like too! )

Thanks again!
