I have tried it with some women I have been with (outside the hobby) but didn't come to love it (pun intended) until this one woman I dated, she told me she was into it and we tried it. She came so hard it was freaky and my own was different, more sudden, no slow build, but hers was so powerful and hot, I wanted to do it more and more. Sadly, my cock is thicker than what she really can handle "Feels like I have to crap for a few days after", not longer, just thicker, so that doesn't happen often.
Its certainly a more dominant type of sex and maybe that makes it more for each person....more of everything, taboo, hot, orgasmic, etc.
