I know the definition of "atypical". I just do not know what is meant by a sexual orientation. Irma does not say hetero, gay or bi, she says atypically. Can she only with fat people? Only in the subway? Or alone? With strangers? No sex before marriage? Or only with people of the same religion? Or what? She is a very open, tolerant and uncomplicated person. She has no problem with the swinger club. Why did she not bring a man/women/other for sex in the apartment during these many months?
