Is it normal that i only get horny once or twice a week and i'm a guy?

Everyone's appetite is different. And that includes how often. When I was in my late teens, I would have lost it if I was unable to be sexually active every day or do. Now, in my thirties, I don't know how I could possibly function at that level. It's perfectly normal.

Depends.. studies have shown that women can have a higher sex drive than men.
