If you watch Stargate Universe you know body switching is a big part of the drama, people stuch on the starship will switch minds with people back on earth and will then be allowed to go joyriding in somebody else body! They meetup with SO's and SEX and stuff happens!
I find this to be appallingly unseemly!
TQC How would you deal with someone claiming to be your SO showing up in a different body? are they getting sexytime?
or If you were the one in the new body and your SO was OK with getting friendly with that new body how would you feel about it?
