(I write from a male Dom perspective, but of course the pronouns can be reversed.)
Can there be anything as downright heart thumping for a submissive at her first time approaching the door behind which she knows her new Dom awaits?
Yes, they have texted, talked, phoned, and vetted. He SHOULD be near perfect, or acceptable, at least be causing no harm. But who can really be certain?
Does he know his stuff, or is he another wannabe? Is he a secret sadist, or will he ignore agreed limits? Will I be safe or will he hurt me in some way? Has my slowly developed trust been misplaced? Can I feel safe with him when I am restrained, helpless? In short, is he one of the good guys I hope he is?
Despite your very best efforts, there are no absolute guarantees when finally facing that door between you and HIM.
There is nothing quite like it in the easy vanilla dating world. So, when that door opens, and he turns out to be perfect for you, sensations over the moon, well--that's hard to match in the van world as well.
To those facing a first scene, or those facing a first scene with a new Dom, here's my strongest hope all those first meeting butterflies disappear at his first touch, or even his first growl --that all the buildup, the vetting, the courage it took to get this far will all exceed your wildest hopes!
