(Female person here)
As has been stated men there are plenty of men in comic book movies who have taken off their shirts. In fact I can't think of one film that I have seen (with the exception of maybe the Keaton Batman films, thankfully) where the major hero has not stripped to his waist and given us a display of his pecs. No one wants to see a woman out of shape.
And honestly given the way that Tessa behaved and was dressed in Westworld, she should be the last person yapping about sexualized women:
The scene might have been inserted as fan service for women given the fact that WW is also a bordello aimed at male clients. But it was still gratuitous and unnecessary.
