..surprise myself just how the subject attracts/irritates me, never been participated in anything "sharing" a partner, nor wanted too, but met some women who have had that misfortune, without exception, they were coerced one way or another into it, call them weak minded or whatever, they were deeply disturbed by the whole malarkey, so, I guess we will read some cunning sophistry from what are, to my mind creeps and perverts advocating of defending the indefensible.....in reality civilized adults would no more share their children with another, any more than they would a partner, that's what love is, to me loyal dedication and adherence to principle of unity, without exception, anything involving a third party is at best a farce..at worst a vile perversion...period...aye the Presbyterian in me still exists ..somewhere...lol

My guess would rather be that if a couple is lacking of communication or simply lived apart they are trying to spice up their life - seeing their love-life as an indicator for the entire relationship. In the end everybody has a free will and is responsible for his own decision.

I can't say whether I think it works or not, although there does seem to be couples where they're together for many years that have the 'open' relationship.
I get quite a few men who want me as part of their 'open' plan, and with their wife's agreement, one even wanted me to chat to his wife so she could tell me she approves.......anyway, I've not been there, I don't think it's right for me though. Also as flattering as it is to be considered sexy, I like to have my personality acknowledged as well.
