I voted for #3 and only now I noticed "If really I must die..." didn't see the die part... LoL I was reading as "If really I must do I want to do it for a "just cause"... (cool video game) ;D
I was once "playing" with electrical appliances and I got zapped by it... my arm was numb for hours and its very painful the following days... so touching Lum would be something similar... or worse. But I would do it... because it's for a just cause... my pervertedness... ;D

Voted 2, not only because it wouldn't be nice, but I'd be too shy for that. xD But I'd work hard to have her hug me for any other reason.
Of course, if Lum was my girl, you bet I'd do it quite a few times a day. :p
