as a girl, MFF threesomes are really bad when the boy is your SO and the girl is a friend. there's two ways this can work out:\n\n1) your SO pays too much attention to the other girl and you feel left out and betrayed because wtf he's your man.\n\n2) SO pays more attention to you and the other girl gets awkward third wheel feeling.\n\nI have been in both... with the same two people... &amp;#3232;\_&amp;#3232;
