In the 1st place, everybody's different. It's unusual for two people to want sex exactly the same amount. Once a day is certainly not too little, for the average guy. With some couples, the guy wants sex more often, with some it's the girl. And then it might change where the guy wants it more often and the girl doesn't, and so forth. And it ain't got a damn thing to do with your good looks and model body. People are people and everybody's different. The way I see it, if you're having sex once a day, count yourself lucky.
Does masturbation count? If so, the sky’s the limit depending on how you’re feeling that day. If you’re talking about strictly sex with another person, I’m thinking that most people only get to do it once a day for the most part, with exceptions along the way. Like one time when I was in college, my GF and I had sex three times in one afternoon.
