Yeah I think attracted to both sexes in the most clear cut definition of bisexuality,  but nowadays lots of people who aren't even bisexual are trying to redefine it (some meanings I've heard it be given is being attracted to any two genders, for example as in liking women and nonbinary people (like people who use they them pronouns) or that it's like pansexual except pansexual people care more about a person's heart or what they're like while bisexuals prioritize a person's genitals/appearance and anyways I admire the whole thing.
