Where should one dispose them, trash or toilet?  For arguments sake, let's assume a hotel room.

Either or doesn't matter to me but if it's the trash it should be wrapped in tissue but if you do that might as well flush it.

Always flush it , it is you in there. Get rid of it. Who knows what someone has in their mind really? WHat if the giel wants to have a baby with an american guy ? Seriously remove the possibility from the equation.She does not need you to get preg if she has your stuff in a sterile bag. The pay off for a baby exceeds 400 an hr for sure ,Kendall Lynn

Recently a long standing MP around me got in trouble when their sewer line backed up.  The city came in and dug it up.  Guess what the blockage consisted of?  Yup, you guessed it.

Pretty embarrassing, eh?

So, I recomend wrapping it up in a wad of tissues or TP and placing in the trash can where it will end up in a landfill or incinerator.

If you are really paranoid about leaving your seed behind, stuff it in your pocket and toss it out at home or elsewhere.

During nearly all of my meetings, the lady will remove the condom at the time she applies the clean-up towel, so whether she tosses it in the trash can, or flushes it, it isn't an etiquette point.  If disposal of this does become your responsibility, just flush the damned thing!

I presume you mean the infamous blue dress.  Yet another reason to prefer that all clothing be removed ...if we're going to make a mess, better to do it on skin  

You asked a good question. I am stunned by the number of providers that throw condom wrappers and used condoms into trash cans. If cops enter their location for any reason, trash will be one of the first locations of examination, followed by beds. Four condoms containing what turns out to be DNA of four males and $1200 under a mattress should be enough for a reasonable doubt conviction, even if no sex act was observed.
