I’m still really new to it but it can be painful to get right but it’s really not painful at all once you’re situated right and used to it. Your balls just go up the front of your pelvis kinda behind and to either side of the base of the shaft. And then everything else just gets tucked away. The weirdest part for me was leaning against the counter while doing dishes and realising that my balls were at the front of my pelvis instead of safely down below and it felt very weird (though somehow affirming) to be sensitive in a very different way.
