I think I'd recommend annabelfatale from annabelfatale.com. I watched a number of her hypnoses, favourites include
Submission toolbox part 1 and 2
Slavetraining Sleep loop (though never looped it), and
Love thy Goddess 3 aka. "Love thy Goddess"
I had the first real ejaculation from The Intoxication above (don't remember though if it happened on the first listen), but the real reason I'm recommending annabelfatale and those clips is, that something has changed in me: I now get a hard on the second I get hypnotised, becoming more aroused the more hypnotised.
At first it was a little distracting, the erection kept waking me from hypnosis, but now it's GREAT. Any decent hypno video is now an HFO, it's AWESOME!!
I am not sure how or in which video she planted that trigger, but I had the first "any hypnosis is gives an HFO" after one time I finished a watching of the Submissions Toolbox and was so horny I was melting.
