The question in the heading was asked by my son to my wife during a Skype call they have every so often. She relayed this titbit to me treating it as a "joke" (and a, "You know what he's like" shrug) which they both "had a chuckle" at. This was after chatting over how he was doing at University, playing in the orchestras there and life in general, and the Universe in detail (he is doing a Ph.D in particle physics).
This "joke" gave me bit of a jolt.

Does he think I am a pervert or worse for wearing a skirt?

And how dismayed and yes, even slightly angry,

in that he seems to think that.

I had thought before this that he wasn't too dismayed at skirt-wearing by men even if he didn't endorse the idea himself. I certainly don't feel "perverted" in any way and am comfortable in myself about wearing skirts but it came as a shock so now I am now sure how to react with him in the future.
So this brings up two questions:-
Am I being over-serious or oversensitive?
And has anyone else had this said about or to them and what was your reaction?
