The main point of my post is also growing my hair to help w/pink fog and wondering if others see similar effects w/underdressing, etc
Yes, I use underdressing (panties daily) and always wear ankle-length leggings and/or sometimes tights and shorts to the gym to reduce the pink fog surge from being away from full dressing for a while. I also find visiting the forum here helps.
The crossdressing community is one that needs to stick together and continue to be there for each other for whatever one needs. We are always trying to improve the forum to better serve the crossdresser in all of us.
