The search for "normal" is a cheeseless tunnel. Sometimes, I go back and look at some of my old "bookmarks" and find links to the "World Sex Survey" that Durex runs every year. There are also many old links about "normal" and what's "average" and so on.
Presenting statistics to your S.O. will not usually sway him/her. What it might do is increase the pressure they feel to "perform" for you, which often tends to result in their heels digging in that much deeper. It might result in them feeling that much more "abnormal" which is always such an effective aphrodisiac, right? Or, if your S.O. is like my W, prepare for the counter-assault, which consists of being presented with every article, survey, viewpoint, etc. which does NOT support your view of "normal." Years after your attempt to prove to him/her that your sex life is "abnormal", well after the time you have realized that it was a BIG MISTAKE to try to convince them with statistics, you will have to endure the articles and books written by people and professionals who share your S.O.'s viewpoint, that it's normal for marriages to decline into sexlessness.
So, let me be the first to ask you this about presenting your idea of "normal" to your wife: How's that working for you?
