I've told a variety of females about my hair fetish, with differing results and reactions. I've also told many of my male friends. None of my guy friends I have told have made me feel any shame about it. Of the few friends who are girls, who I was not interested in sexually/didn't have great hair, they mostly reacted slightly curiously but didn't get too in depth into asking questions.
I've had three sexual/romantic partners that I openly told my hair fetish to. The first one was a woman I dated in my early 20s. We dated on and off, but mostly on, for a year. She had mid-back, naturally straight dark hair that I couldn't get enough of. She was the first woman I had been with that really did it for me in every single way on a physical level. Pretty early on, I told her about my fetish. Maybe 2 months or so in. In the beginning, when the relationship was still good, she was cool about it, and was happy to let me play with her hair and feel it during sex.
When I told her about my desire for a hairjob, about 4 months in to the relationship, she did shame me. She told me she was willing to do "anything" with me sexually, and when I voiced my desire to feel her hair on me sexually, she said "that's really weird" and made me feel shame about it. Our relationship became toxic, and over the next few months I began to really pull away and resent her, partly for that moment, and she started indulging me more and more in my fantasies. She let me have hairjobs, take pictures of her hair, video hairjobs/blowjobs etc, and while I was glad she let me do it, the feeling of love wasn't there and I never fully recovered from her initial reaction. I felt really vulnerable and she made me feel like shit after making me feel super safe. I was hesitant for a while after that to open up again.
A few years later, I met a girl who was very sexually adventurous. While I did enjoy her company and was somewhat attracted to her, she definitely was not what I was looking for in terms of a partner. We had an 8 month or so fuck-buddy situation, and for a while things were decent. Her hair was naturally wavy, bordering on curly, and I really prefer straight hair. Throughout that 8 months, her hair got pretty long, and she definitely let me indulge in all of my hair fantasies including letting me cum in her hair. She never made me feel shame about my fetish. She actually did show interest in understanding it and was accommodating. But the deeper connection wasn't there, and she started to get strong feelings, so I ended it.
My current relationship is the best situation I've been in so far. We have been together for a year, and very early on, she became informed about my fetish. I no longer felt a deep sense of shame, and I knew it was going to be important as I could see a future with her quickly. She too had slightly wavy hair, but she quickly adapted to straightening it for me and has grown it quite long. She lets me touch her hair, use it during sex, gives me hairjobs, and overall doesn't shame me for it at all. The only negative is that her hair isn't naturally straight, so she sometimes complains that it takes her longer than she'd like to get her hair "right" for me. She just got her first brazilian blowout and the results are really good. She says she wants to keep getting them.
I do worry that one day she may tire of going through the work of keeping her hair straight and really long for me, as she is not interested in keeping it long and straight for herself. She definitely sees I enjoy it and respects my desires. I have tried to explain how the fetish isn't a conscious choice, and I am overall a really good partner to her as well, so I think she feels it is worth it. I hope that continues.
