Condom riddle

[desteffy]

I heard this from a mathematician a while ago, see if you can solve it:

Suppose there are two guys and two girls. Each guy wants to hit it with each of the girls (with protection). How can this be done so no bodily fluids are exchanged between different people using the fewest number of condoms. Obviously this can be done using 4 condoms. Is this possible to do with 3 condoms? with 2?

[edit] No washing them off!

 

[KydLynx]

1, just wash it off each time and swap with your buddy.

save a couple bucks while your at it too. :beer:

 

[FleshLight]

Guys each take condom and wraps it around his stuff to seal the passage way. Nothing comes in or out.

 

[jagec]

ANY bodily fluids, guy or girl? You need 4.

3...double bag guy a for girl a while guy b takes 1 condom and does girl b....guy a then takes off outer condom gives to guy b who does girl a....guy a does girl b with inner condom.

you got the right idea. see if you can be even more creative and do it with 2.

 

[desteffy]

or explain why its impossible with two

2, with 1 unused.

Triple bag dude A.
dude A --> dudette A with outside (third) condom.

dude A peels off outside condom and gives it to dude B.
dude B --> duddete A with outside condom.
dude A --> duddete B with middle condom (and dude A is done)

dude A peels off middle condom and gives it to dude B.
dude B --> dudette B with middle condom (dude B is done)

Dude A is left with clean condom. Only 2 were actually used for the acts.

Your still using all 3 condoms, considering you can't exactly return Dude A's "unused condom."

Guy A does girl 1 with a condom.
Guy B does girl 2 with a condom.

Guy B takes his off and guy A puts it on over his own condom (nasty).
Guy A does girl 2.

Guy A takes off Guy B's condom, gives it back. Guy B puts it on. Guy A takes off his condom and gives it to guy B. Guy B puts Guy A's condom on over top of his and does girl 1.

wait. that wouldn't work as guy B's juice would contaminate the outside of guy A's condom and would render it useless for going at girl 1.... hmmm.

Figured it out:

Guy A puts on both condoms. Guy A does girl 1.
Guy A takes off outer condom and does girl 2.

Guy B puts on the outer condom that Guy A used and does girl 1 with it.
Guy A then gives Guy B his used condom. Guy B puts it on over top of his condom and proceeds to do girl 2.

Each guy uses 1 condom. When they are done, they turn them inside out. (assuming they dont blow their load)

The chick's fluids are all over the outside, and yes, they do blow.

Yes thats the original solution we came up with. your other works, but this has less changing.

 

[Drakkon]

Ohkay heres answer to 2

Guy A double Bag does girl A
Guy A gives outer to Guy B
Guy A does Girl B with inner
Guy B does girl A with outter
Guy A gives his Girl B condom to Guy B
Guy B puts new condom over used and does girl B

sick if u ask me but its a solution....

Actually it doesn't work. When guy B gives his used condom to guy A, his jizz gets all over the outside of guy A's condom. When they switch around, guy B gets girl 1's stuff on him on the inside of his condom, and he also has his jizz on the outside of the inner condom guy A wears and uses as his outer condom to do girl 1.

 

[MercenaryForHire]

None; for asking such a question, the mathematician will never be either of the two guys actually getting laid.

Edit - Teh gud speiler

- M4H

I have a funny story about this riddle. I was in a high level CS class that needed instructor approval to get in. Well, on the day of the Microsoft interviews most of us got one, and we were tossing around questions that came up in the past.

Then this question came up, in a sligtly different form (how do you have safe sex with 3 girls with 2 condoms?)

The drawings on the board to convince one random person it was possible were . . . amusing. The prof. must have been wondering wtf we were doing before he arrived.

BTW, can you abstract this to n girls and m condoms? It's a little tricker then you think
