Different Strokes for Different Folks and to each their own.
There is a group of swingers who blatantly go and invite friends around me (including my swinging partner) to their own parties and they don't invite me because I do not conform to their "body shape" standard... fair play to them. Good thing that the fem party organiser body shape does not conform to my swinging partner standards! *haha* I have to confess that she conforms to mine but she doesn't fancy me... *heartbroken*
Not to worry, there are many other parties around there... for that party that I don't get an invite, I get six others. ;) Too bad I am kind of taking a break from parties now, but beware when I come back! hehe :)
It's their party. They can invite whomever they wish, at the end of the day.
