Not exactly the same thing as spanking, but caning is a simpler alternative. You just use a thin wooden dowel or a thin, flexible stick, and wack your ass with it. It's a sharper pain than spanking, and I prefer the pain and long lasting sting of it. Just be careful: I get really intense when I'm horny, so I caned my ass hard earlier this week and then had a huge cum. Wasn't till afterwards that I realized I had drawn a little blood! I welted up some and boy was it sore for a while! Anyway, ask your Dom if this will be a suitable alternative. It's much quiter and much more painful!
