I want to meet the man who would invent portals and have the first thought of "Now I can forget myself"
I'm still not sure that you'd be able to forget yourself if you had portals.
Like, if I were to have two portals lined up opposite of each other, then if I was stood in between them I would see the back of my body, and could reach through and touch it.
Now imagine I grab my bum and try to put my willy in it. I'd be thrusting my hips forward in order to do so. But of course, if I thrust my hips forward, my bum moves forward too, which would be away from my willy. So, it would be impossible to actually do any thrusting movement, which is basically what creates all the stimulation of love.
This could be fixed somewhat if the portals were very close to each other, so that stood inbetween them I am literally pressed up against my back. But then how do I even get into a position like that, if I have to squeeze into a wall.
I suppose the walls could move towards each other and then the portals could be activated, but that still wouldn't solve the issue of actually moving your body once you're in.
