I became fascinated with wetting from wet dreams as a kid. I'd wake up with wet undies after one so began re-creating the 'dreams' by wetting my undies a bit before wanking. Later I switched to my speedo briefs so my parents wouldn't wonder why my undies were wet all the time. I LOVED the wet slippery feel of the speedos so began completely soaking them as a part of wanking and still do today!! I added some panties to the mix as a teenager which I think feel very similar to speedos.
