wow glad to see so many open minded people on this subject.. from experience they can go either way bad and good... it always depends on everyones mind set. i have had many with my man and for the most part all has been good.. and even a little more than threesomes ( multiple people aka guess you would call it an orgy lol). it depends on what you and your other half are looking for, as long as one party doesnt become so emotionally attached ( including your guest or guests) that it inteferes with your relationship... good luck all to what you seek for your fantasy
