I was writing a scene where a guy was choking another guy to death. You can go online and type 'chokeholds' and watch scenes where martial artists choke each other out. You can hear what noises they make when they go unconscious see how their bodies flop and everything. YouTube is amazing for the more detailed stuff.
However saying that I totally support the concept of civil partnerships in the eyes of the law and think it a disgrace that same sex couples have had to wait so long for legal rights protection and recognition.
