Is it normal to lick and smell dirty socks

Okay, so dirty stinking socks. Biggest turn on. I'll get my friends to take off their socks after wearing them all week and they are so stinky and dirty and smelly and I'll get them to rub it all over my face and force me to smell it and lick it. I just love it. I start by running my tongue all over the outside that is so dirty and they often walk around and outside without shoes on. Then once I've cleaned that with my mouth I turn it in side out and lick and smell the inside the part that has touched their foot for the last week or so. Amazing then I will lie down with my face in a pile of them and inhale deeply. The best is when your being forced to lick and smell and sniff them for ages. And they will shove the dirty socks into my mouth and make me enjoy it. I love it!!
