Your skin will grow thicker and it will take a lot more punishment without getting cut or bruising. Humans are animals after all, and we didn´t have shoes or clothes 200.000 years ago in Africa. Even today, you can go see videos from Brazil of people playing football barefoot atop the pavement.
But that doesn´t mean you´ll be comfortable. Even if you don’t get cut, it doesn´t feel nice to step on pebbles, or branches, or anything else. Modern society loves it´s hard surfaces, which as you can imagine can be rough on someone´s soft flesh. Any kind of seat or sitting position that puts weights on the groin is a no-no. Genitals be sensitive, yo, even if they aren´t balls.
Speaking of, you´ll also get dirty and will need to constantly clean or scrub yourself. Clothes protect you from the dirt and dust of the environment, which would otherwise stick to the skin. Depending on the temperature, you can add a thin layer a sweat to the mix of icky things covering your body. In that case, the girl will also have to watch out about leaving wet imprints of her ass whenever she sat (assuming she cares about that sort of thing).
