Yes, but the features of the approach are quite different. Men get approached a lot by folks who are selling stuff or fundraising, also by bums/homeless folks. Women get a lot of approaches for personal intimacy, and these do get quite tiring after a while.

No, in this case the attractive man also get's "approaches for personal intimacy" in the same sense that the women gets "approaches for personal intimacy" (she probably wouldn't label them that way)

Yes, women have to care more about personal safety, out of necessity. Most people are aware of that.

But you deny it above. If I want to interact with another person then it makes sense to factors like that into account. Triggering someone else fear is not good.

Let's say I meet with a group of four people. 3 of those have little anxiety and are easily hugged. The 4th person has some social anxiety and will likely feel a bit uncomfortable when I hug them. If the 4th person is a girl I likely won't force a hug on her. With a guy I often will still hug them. Not hugging them might mean to him that I don't respect him because he's the only person I didn't hug and that might be worse for him then the slight uncomfort of being hugged.

But try walking around the sketchy part of town and telling me that some folks don't make you uncomfortable.

I do have habitable triggers but if I want I can clear the feeling whenever I want and I will clear them when looking weak would probably make me a more unsafe. Then I'm not typical.

I'm weighing 55kg. I don't look very threatening. I had decent presence because I was coming from an evening dancing but I didn't do anything nonverbally that would warrant someone feeling threatened.

subsequent changes in behavior, not that there's any difference between genders.

For practical purposes behavior that correlates with gender is difference between genders. Behavior is what you care about when it comes to modeling other people for interacting with them.
