Nothing really hurts me, I just want flexibility and relaxation. Is this for me?

Of course, and we have plenty of clients like that. Pain is not a requirement: many come for mobility, lightness in the body, prevention, and simply for deep relaxation after a workday. Beyond lengthening the spine, it's also a reset for the nervous system: the body finally lets go of tension, and after a session many feel calmer and lighter. So coming 'before it starts hurting' is actually the smartest scenario.
