So... Usually 9 out of 10 times I've courted a female with really long hair, they pretty much already knew I had a fetish. Although, coming clean about it does help. It saves a lot of embarassment along the way, making you seem a bit more high-strung... which also tends to make whoever you're trying to date want to not talk to you. I'd just say it plain and clear. If she accepts it and stays your friend, then you've succeeded. If she gets weirded out, then move on. There's plenty of fish in the sea out there. Either way, you'll feel better about yourself in the long run.
