question for guys

I went through a phase where I thought anal sex would just be the most exciting thing in the world. I think I thought that way for the same reason I like Pepperjack cheese. It's in my DNA because I am a man. Maybe linked to testosterone levels. My wife is pretty straight minded about sex though, and said she does not want to do anal. Since she is the love of my life I aquiesced. I got over my anal fetish after a while, and it no longer bothers me. But my wife does like to have her anus massaged, if I work up to it slowly, it makes her moan and twist with pleasure. Apparently it is a very sensitive area, probably for most women but not all, so I can see for some women it would feel good to be penetrated there.
