39 year old male here. Switch, I like to be dom but learn more when I am sub. I find this site very erotic and am listening to several files right now but still waiting for a breakthrough. I am heterosexual and not interested in changing that but would like to know what it feels like to be a girl so...

I am sorry to be asking a stupid question but I am new to this. What is the difference between the binaural files and the regular files? I downloaded one and I can not tell the difference. Also what are subliminal files? They don't put you in trance do they? Are they made to use as background noise?...
