Is it normal to get turned on by wife pleasing other men more than me?

I get very Horny when watching my wife get fucked by another man. Then when they're done it makes me last longer when I fuck her. Ok the other people who say it's wrong, that's their opinion,and they are entitled to it,but if you enjoy it,who gives a crap what they say,their probably not getting any,so they get mad at you cause you are. Do what you feel like. If yo love it then to hell with what anyone else thinks
