Have you ever wanted to video record the time when you are /making love/ having sex with someone? Then on your next session with the same person, you view that clip together while doing it again?
I was doing it actively when I purchased a GoPro. Later, I added two more to give it more ‘angles’ and I fire up my PP and start to edit the scenes. Most of the times the boys know and consented, sometimes I just ‘fug it’ and record anyway, some would protest, some just let me record anyway.
