A buddy of mine and I were flying to Seattle about a month ago and had a really good experience with flying. I went thru just fine and he was right behind me. He got pulled out of line and was brought into a room. He said the groped him all over and felt up his package, balls and passed with flying colors. He wears an STP pretty much 24/7. He said the TSA agents never batted an eye nor did they question him about anything. He said they were friendly and respectful. If they knew he was an FTM, they never let on.
