My new casual partner has mentioned this.
I realise it's probably pretty standard but having been in a very sexually boring LTR I am new to this.
When is it 'nice' to do this? During oral, or the main event? And how, I don't really get it. Just find the Hole and press a finger in. For example if he was on top, would I reach it from underneath? Also which finger. And when do I wash it? Straight after, I would think. But does that kill the moment? Also how long to keep the finger in?
And my nails are long. Would I need to have short nails for this.
Could someone please go through the basics of this please. Thanks
