Some unique factors of Pythagoras is that he wasn't interested in math but formed the school that is of great mathematical study in its time. He followed a list of rules that pythagoreans followed, some without explanation; he would not eat meat, and stuff.
Pythagoras never commented on his sexuality, and it has no bearing on his contributions to the study of mathematics.

Pythagoras (570? BC- 495 BC) is recognized as a philosopher and mathematician, one who devoted his life to the study of numbers. He recognized how mathematical concepts related to everyday life, and created a school to encourage future scholars. He developed the religious philosophy Pythagoreanism, which eventually came into conflict with the established religions in Croton, a Greek city in Italy. His studies led to discovering the mathematical nature of music. The Pythagorean Theorem, which relates the lengths and angles within a right triangle, is named for Pythagoras. (see related link)
