Yes, sexual harassment involves many things which fall far short of sexual assault. And, sure, maybe those are first world problems -- if you want to run a successful business in the first world, then you shouldn't be surprised by the need to address first world problems.
And, sure, maybe some women like playing hard to get. The existence of those women does not create license to continue to pursue any woman who has turned you in the workplace. Nor does it remove the legal obligation of the employer to address such unwanted pursuit. What you do when pursuing women who are not your coworkers outside of your work environment, so long as it comports with the less restrictive laws applicable in such environments, is your own business.
Also just because there are worse things than verbal sexual harassment doesn't mean it should be ignored.
