I personally love getting my hair pulled, found it out because my last lover tried it and omg I loved it. As long as he didn't pull too hard... Also I have a bit of a hair fettish. I play with my lover's hair all the time, I donno I just love the feel of it
Also when he's going down on me I always have my hands in his hair, and when it feels good I tighten my grip, it's a reaction that lets him know what feels good
And hey if hair pulling is wierd then I'm super wierd because I also like to scrach (although I don't have nails right now) when he's on top, and bite, and nibble, and kiss, and what ever else
Just do what you like and if your partner has an issue with it don't do it, find something else, and visa versa, you gotta speek up and say "ouch" or "please don't do that" or something to let him know that you don't like that... and if you do have fun with it, never be afraid of trying new things
