Maybs its cos of the lack of nookie he gets
but when old flame Miley Cyrus wasn't satisfyed due to his frigidity... Nick Jonas seeked other ways to get himself haps down there
apparantly fingering himself with his purity ring, (TOTAL ABOMINATION OF WHAT THE DAMN RING STOOD FOR!) he likes to look through photos of the Hannah Montana star butt naked or occasionally wearing her see through victoria secrets which have apparantly given the diabetic jonas "uncontrallble erections"
sick.
the whole lot of them
we have kev whos ba''ty making out with some immigrant, taking the whole "mi casa tu casa" thing to a new level
joe whos a man whore and does "occasionally get hard"
and then nick, who defiled his PURITY ring by getting substances on it...
lets hope that "bonus jonas" Frank Furter won't decieve the public like these 3 rascals did
