While girls and women call themselves 私(わたし or わたくし)most of the time (apart from regional variations), men call themselves differently.
- 私(わたし or わたくし)- formal
- 僕(ぼく)- boys use this first and later learn to use other words as they grow up
- 俺(おれ)- young men often use this in casual speech.
- わし – older men sometimes use this in casual speech.
