My friend,
I do not encourage you to wear FBT shorts in public.
The society will not accept it.
If you notice, the men's pants is getting longer and longer (I
am talking about short pants), such that nowadays it is neccessary
to wear bermuda at knee-length.
Meanwhile the ladies' ones are getting shorter and shorter, such
that they can wear almost FBT length short, but, with a different
cut (called shorts or hot pants).
Therefore when you wear FBT shorts, this may be miscontrued.
You may be mistakenly giving the impression that you are
gay.
However,
For some instances this may be excusable, and some occasions and
settings can give you a cover.
For example, afternoons on the beach.
Try to do some small running and jogging also.
This may give the wrong impression that you are a sportsman who
are excercising, and you are not gay. Thus, you can satisfy your
fashion choice safely.
Remember,
Try to give a macho cover such as a sports setting.
Otherwise it diminishes your masculinity and increases your
feminity.
