You should not normally smell that at all. You're possibly out of practice?

You shouldn't be smelling your clutch burning. Unless you're revving the engine and slipping the clutch on starts or between shifts, a quick hard shift with proper clutch engagement won't cause the clutch to smell. Porsches can have interesting odors after a hard run, from cosmoline on newer cars, rubber dust kicked up on the exhaust, a bit of oil on a hot engine, or brakes, for example. Are you sure what you're smelling is burning clutch? If so, not good.

Then I guess we could say that burning clutch smell is normal for the way you shift...

Yes it should be smooth. Make sure you have your technique down with smooth starts and shifts at slower speeds where you're passengers heads are not bobbing around before you start trying to do quick shifts. Shifting properly requires a proper rhythm between the amount of throttle input you are giving the car and the speed of your shift and clutch engagement. Don't try shifting fast when you motoring along in traffic at part throttle; that's the time for smooth, relatively slow clutch and shifter action. When done properly, the shifts should be as smooth as an automatic tranny and your passengers should barely notice. When you are giving the car more throttle your clutch work should be quicker; if you hold it in too long after upshifting it will have to slip when you re-engage it. Shifting properly is an art that must be practiced.

If you are slipping the clutch too much with poor starts or shifts it creates additional friction which makes heat and literally causes the lining of the clutch surface to "burn". This will definitely shorten the life of your clutch. Both my kids learned to drive with manuals and honestly, as much as they struggled at first, they never burned clutches. You must be dishing out some fairly serious abuse with high rpms and lots of slippage etc. to be smelling your clutch. Go slow and save the fast shifting until after you get a better hang of it. Good luck.

I've been driving manuals for years, and I think I sometimes smell the clutch when I park the car in our garage. It's possible it's another smell, though.

The driveway is sloped and the garage is a tight fit. I don't rev it that high, but I've got to let the clutch out slowly so I don't hit the shelves. I don't notice the smell any other time, only in the confines of the garage, which makes sense, I guess.

As with any racing advice:
Smooth first, Fast second.

It's like sex - if you don't have technique, you're not going to impress with speed.

Hot engine smells like cosmoline and oil. The harder you run it the more you will notice it after parking. This is a good smell. Burnt clutch is very different and noticeable from inside the car while driving. Not so good.

Maybe get an experienced driver to ride with you and check your technique as well as the smell - it may not be clutch smell. In all the years of driving manuals, I don't recall ever burning a clutch or smelling it - even when I sucked at it and was just learning. My car comes in with a fairly bold odor if I drive it around aggressively in Sport+. And I hope the clutch isn't slipping. I think it is just HOT engine - the fans usually blow a while too afterwards.

Never aim for speed when learning, just smoothness - you don't want your date distracted by lumpy shifting while you are trying to be cool in you car. And a quick jerky shift is pointless during normal driving.

After you get so that every shift is smooth, being fast when necessary will come second nature.
