I read enhancing one's sexuality first, but now I'm unsure how that would work for women. However, it should give a decent and outmost flexible penis ring. Also very valuable addition is this firm-up-and-extend-circumferrence thinger. Fun for ball gamers..
Nothing for people who not shave, though.
Disturbing enough, I vote "Damage control in space", hell, you never know!
Going to date a hot Vulcan chick? Spend 5982 bucks on renting a hot 653 litre space cruiser to stretch out dat ho over at the mercury cliffs? And now she refuses 'cos you used up all ya duct tape to tie him back along the notch and make him keep dang and lang in the dark thight tunnel of the poopoo-trains so you both could do the lesbian thing? She just kicked out the window and left and you might want to fix that thing while you can hold your lungs in your body? TENSED? No freaking duct tape anymore?? -- Not going to be the best situation in your life, I tell ya.
