@freemo No problem.
As for the question in terms of how she would feel: it depends on if she likes you. And this isn't a woman only thing.
Let's imagine the inverse scenario: you're wearing fairly tight shorts and *insert movie star/celebrity you find attractive here* walks up to you, eyes your bulge for "a solid 2 seconds" and then continues talking to you respectfully. Well, if you consider a lot of factors (e.g. are you married, is she married, do you find her attractive, etc) you'll come to a conclusion as to whether you appreciated the gesture (note this happens in milliseconds and is not a conscious decision). Now, imagine instead of *movie star/celebrity you find attractive* we have the human personification of Roz from Monster's Inc do the same thing. You may not appreciate the same gesture, because you may not find her attractive.
Now, let's imagine that in either of these scenarios, the woman in question asks you "hey, can I look at your bulge for a few seconds"? I imagine most men would respond either internally or externally in the following ways: a) is this a prank? Is she serious? Why would she want to? b) That's a really weird question to ask, and the fact that she did so means I kinda don't want her to, or c) Sure, ogle away. Though I suspect most people would fall into categories a or b.
So, overall, all people judge behaviors, particularly ones in a semi-intimate context, based on how the evaluate the person. If they like the person or are interested in them as a potential partner, this helps "smooth over any rough edges" the person in question may display. However, if a person has already judged you as someone they are either ambivalent towards or actively dislike, this magnifies the impact of behavior that is close to "the line" and may even move the line further away from this sort of behavior.
All this to say: you can't apply the same behavior to different contexts with different subjective personal preferences and expect the same result, so the question is kinda pointless unless you're directing it to a specific individual with a specific target and context in mind.
