Hi, Veronica !!! Your comment is good advice. Indeed, It is a part of truth. But, there is a little misunderstood. Both sexes can also use "わたし" naturally. And "おれ" is a little rude word like kids. So I recommend using "わたし" in all case. [Exception]: (1) In case of talking to friends. (2) Boy (3) Rockstar or outlaw.

A quick note on pronouns: わたし is a way of many of saying "I", b u t, it´s mostly used by women, for men it's usually おれ
