Congrats! I have a similar experience. My girlfriend has been growing out her hair for the last 2 years for me, and also has very thick luscious hair that she also straightens to perfection for me and takes really good care of it. I've had so many hairjobs and she knows her hair will be in my hands or wrapped up in my face while we have sex. I used to dream of this growing up, and in the last few years I've had a few different women before my current partner be willing to engage with my fetish, but she's by far the most accommodating and loving about it. The only way to get what you want in life is to ask for it!
