I have a strong opinion on this subject that I would like to share with the group. Mind you, this is not directed at any one individual. I just think it is something we should consider.
I personally think it is unfair to the medical staff. After all, if this is a scheduled appt., then you as a cd, have the choice as to what you will be wearing for the appt. The individual crossdresser may not be embarrased to go in wearing feminine underclothes, but I believe we must consider just how it might make the people attending to you feel. This could be very embarrasing for them, putting them in a situation that they may not be comfortable with.
If the individual is going through as process such as SRS, and the medical staff is aware of this, then it may be acceptable. But to just spring this on them merely because the crossdresser wishes to be "noticed" for whatever reason, in my opinion is selfish and unfair to the others involved.
We all have our own reasons as to why we feel the need to underdress for certain situations in our lives, but I think we should also consider the other people we involve in our actions.
I personally dont endorse the practice of underdressing for Dr. appts. for the reasons I have given above. I would welcome any comments regarding my thoughts.....
