I'd like to alter my previous post.
As a rule, GGs don't get propositioned in the manner that some people here have described, in day to day life. Maybe men are more blatant with other men or TGs because they are ruled by the same instincts as the objects of their admiration and deep-down they know that their sentiments will be understood.
I'm not saying that GGs never have to fend off unwonted advances, but it tends to happen more in certain types of situations, like clubs and bars, and it doesn't tend to be as crude. Maybe men are generally more courteous with GGs, unless the GG is in business for herself. In the normal course of the day while out and about, GGs do get flirted with and of course every once in awhile there will be a creep who feels entitled, but these creeps are few and far between. When this happens, it is indeed scary, because we don't have the same physical strength as guys.
And I'm not saying it is the case with everyone who has been approached, but there is also such a thing as sending out signals, even if someone doesn't want to admit to themselves that this is what they are doing, so of course my comments do not apply in this situation.
If your attitude when being approached in a flirty manner (assuming you are not out in clubs and bars where there seems to be a license to pick up people) is that the person is just being nice, or social, then it is easy to deflect the attention whether it is an imagined come-on or not, without being rude or without feeling you need to run away. Just carry on with the conversation until it is time for you to move on. But, if you are going out dressed, then I'll admit there are a slew of guys out there who do want T-girls and they do see you as someone with a bonus between your legs. If you're not interested, these men will need to be handled more firmly than most GGs would have to handle most guys. So the advice here is spot on.
