Michael Ian Black speaks from experience:
Male libido is assumed to be a constant, quivering thrum. For some men, maybe it is. But for me, as much as I enjoy the old in-n-out, the rubba-dub-dubba, the squeak-n-bubble, I have never craved it the way our culture has led me to believe I should, not even during my fabled Horny Years from ’91 to ’95. Except for those moments when I was in the first throes of a new love, sex has never subsumed me. Yet every cultural message I receive has led me to believe it should. Consequently, my lack of nymphomaniacal tendencies has always left me feeling embarrassed and emasculated.
His deeper message:
To me, sex isn’t even about sex. Fundamentally, it’s about acceptance, having somebody desire you enough to allow you to envelop them and wanting that person to envelop you in return.
Recently Black also critiqued Hollywood's version of love:
Hollywood has given us two, equally false, notions of marriage. Either it’s the joining of two gorgeous young people "destined" to be together, or as a wheezing and cold institution inhabited by miserable and middle-aged wheezebags, usually meant to illustrate a counterpoint to the love the gorgeous young couple in the film will share once their destinies are realized, and they are able to finally be together against all odds. Yawn. Boring. Wrong. …
It’s doing laundry. It’s paying bills. Cleaning the kitty litter. Marriage is a hundred thousand tiny tasks you share. It is peeling vegetables and changing lightbulbs and giving each other quick kisses and wishing for each other "a nice day." It is coming home and smelling dinner cooking, and running out on a cold winter night for antacid because she has a headache and cannot sleep. Sometimes marriage is being pissed off at each other for weeks at a time. And sometimes it’s walking into your children’s bedrooms and watching them sleep.
