I was thinking today about how sex is the hardest thing to research. You can research the build up but the actual act is an entirely different thing. I can be lying there, with my writing brain switched on trying to capture the feelings, the thoughts, the physical sensations but then I realise something -- it's BAD SEX.
I can't have my writer brain turned on during good sex; the two things are mutally exclusive. Good sex makes my brain go mushy. Afterwards I've been told I've done things or said things I can't even remember. That doesn't make for good research, but it's a lot of fun.
I don't know how other people do it.
