I have listened to the file that trains you to enjoy oral sex with mens penises almost a year ago and only listened to it 2-3 times before giving up thinking it failed. After a few days I had started to develop a fetish for cock sucking (it is now my second favorite right next to hypnosis). It didn't matter who or what gender was sucking cock, I loved it all the same.
Since the time I listened to it I have loved to watch people go off on pleasing guys cocks, but now I actually crave on performing fellatio myself. I have had fantasies today about buying a dildo (the bigger the better) and not useing it for anal (I'm a guy) but I want to use one for oral pleasure. Just the thought of sucking on a dildo made me horny. I haven't had this desire before but today it appeared out of nowhere and I love the feeling. I am actually tempted to listen to that file again to make me want it more.
Also since that file worked so well I may try the train anal file to see if it has the same effect.
