That would be gay. You're travelling to a different point in time to suck a dick... not to get blown.
No.....cause I don't have the urge to suck dick. Not even my own! Now if my future or past self were down then maybe I'll let me blow me but the twin paradox would scare me to much to travel to a time where I'm alive.
Wtf? like seriously how did you even came up with this thought? like were you just sitting down thinking about sucking your own dick? Come on bro.
