Asking somebody out isn't sexual harassment. Insisting and making crude work-inappropriate remarks is harassment, and that's not just in the US: [76/207/EEC] Article 2 § 2

> harassment: where an unwanted conduct related to the sex of a person occurs with the purpose or effect of violating the dignity of a person, and of creating an intimidating, hostile, degrading, humiliating or offensive environment

> sexual harassment: where any form of unwanted verbal, non-verbal or physical conduct of a sexual nature occurs, with the purpose or effect of violating the dignity of a person, in particular when creating an intimidating, hostile, degrading, humiliating or offensive environment
