paragraph_text: Sexuality and gender
  
  Male sexuality and attraction varies between individuals, and a man's sexual behavior can be affected by many factors, including evolved predispositions, personality, upbringing, and culture. While most men are heterosexual, significant minorities are homosexual or bisexual.
  
  Most cultures use a gender binary in which man is one of the two genders, the other being woman.
  
  Most men are cisgender, and their gender identity aligns with their male sex assignment at birth. Trans men have a male gender identity that does not align with their female sex assignment at birth, and may undergo masculinizing hormone replacement therapy and/or sex reassignment surgery. Intersex men may have sex characteristics that do not fit typical notions of male biology. A 2016 systemic review estimated that 0.256% of people self-identify as female-to-male transgender. A 2017 survey of 80,929 Minnesota students found that roughly twice as many female-assigned adolescents self-identified as transgender, compared to adolescents with a male sex assignment.
