Hi everyone, there was a couple on here asking if there is a 'secret symbol' - is there a FMF/ MFM/ FF/ MM symbol?!  I am also interested, because I would like to place it on my business card. And, maybe even place a sticker on my quarter window on my car. 

 I have come across the upside down triangle. So, is that 'it'?!

 Interested in everyones thougths/ ideas!  Bye for now, V
