Awwww shit man, i'm a dumbass though... coming up with theories is like super hard for me... ummm... my finest theories are 'Sensei has a big penis' and 'sex make peepee feel good' which, yes, are incredibly complex and compelling theories but both were constructed using every ounce of big-think juice my brain could produce. I have been toying with a a new theory but it's little more than conjecture at this point, revealing it at this time could easily turn out to be premature but since you requested it and it's all i've got i guess i'll share it... i'm thinking that maybe, maaaybe, Sensei very horny...
Please be gentle of you think it's ridiculous, like i said, i haven't worked all the kinks out yet so i'm not very confident in it.
