OK - first - I really do love you intp men. Logical - always (for what it is worth men of other types love Male-o-drama, just are too emotionally stunted to see it in their own lives). Coupled with that is your sincerity - makes my knees weak.
I have been in the world of open relationships and frankly, you all nailed the biggest flaw - women are in short supply and until there are more ENTP (insert other types?) women in the world, this is not going to change. Too many men for to few women who can make it work.
SO that is why that is not the critical factor. I realize that with the right 1 person (more Ti - yum!) I would be very happy in a close closed relationship.
I enjoy the experiences of having had an open relationship, but don't have my heart set on becoming a female douchebag (yes, they exist). It makes me sad honestly to see that the playing field of sex will never be level and I would be the first to tell a whiny woman to shut up about not finding good men - too many to choose from - really!
All that to say, the outlook Is hopeful - spiritual (insert your own word for human open to new possibilities/existence in another parallel universe ) intp men DO exist
THANK YOU - joke away if you want about OR. I think they can work, will work in our society at some point, but frankly we are too sexually repressed and immature for it to work at a large scale now.
