Is it normal to put my faeces in my wifes vagina?

This week my wife complained that our sexlife was boring. We were into straight bdsm since we met, i was happy enough but it turns out she wasn't, she was bored. I suggested getting the neighbourinvolved but she had done this before with someone else and the neighbours acted strangely around her afterwards. So that was no good. She told me to open my mind and think of anything i liked and to do it to her while she was tied up. We played watersports alot already so i thought maybe involving faeces might be differnt enough for her. So i tied her up legs, spread, and smeared a dump that i had done earlier into a Tupperware container around her vagina and tried to push some in. This didn't work so it fisted her with a faeces covered hand. I thought i had hit gold. She was writhing around in what i assumed was pleasure but this wasnt the case. When i took the ball gag out of her mouth she went crazy, shouting and swearing at me like a lunatic. I had to leave her tied up, so that she could cool down, while i haf a long bath. Is it normal to do what i did? She pushed me into it we were into hardcore bdsm and watersports i didn't know what else to do.
