Either soak and peel as mentioned by a PP or grate the tomatoes, the skins stay on the grater.
I only use fresh tomatoes for one type of sauce (crudaiola), where you leave the chopped fresh tomatoes to infuse with garlic, oil, salt and pepper for an hour or so, then mix into the cooked pasta. No cooking required and lovely and fresh in the summer.
For all other sauces I’m lazy and use Mutti. I never add sugar, with Mutti you tend not to need it, but if the tomatoes are tart just add a tiny pinch of bicarbonate. Make sure you use a good quality extra virgin olive oil and if you use a soffritto (chopped onion, carrot and celery) make sure it’s chopped really finely and soft and sweet before adding the tomato.
There is no hard and fast rule for the herbs or spices, every family has their recipe. Herbs are usually fresh basil or a pinch of oregano, as for spices the only one I’ve seen used is a pinch of nutmeg as that also takes down the acid. It’s usually used in ragù (bolognese sauce) and I only tend to use it in veggie ragù. Wine is used for more structured sauces usually, for a simple tomato sauce it’s left out, not least because it can add to the acidity.
