Well i think sniperkid is fuckd up for starting this for one!
but tbh i reckon he doesnt get much or the fact hes gay or him and cortana have like virtual sex while doing missions i mean shes in his armour so there for hes bound to be like naked in there coz i mean holy shit its gunna get hot so she could be oing a bit of cock sucking right there and all he feels while punching some grunt in the head is like little electrical sparks tapping and zapping away at his giantromonasaz cock because (genetically enhanced!) and therefore he gets his sex through cortana i mean when hes not fighting hes going to a battle zone or hes frozen! haah so either way he fighting or sleeping so the sex has to be happening when hes fighting!!
