Maybe he really was a Princess in this world, not a Prince. When he had just transmigrated into this world for the first time, his ass flew in the air, and another man was ready to enter him from behind.
He wasn't the one who was going to enter the tight hole at that time, and Bai Chen knew that he should have questioned his identity from the start.
Physically, he was still a man in this world, but his role was that of the 'receiver' here and was no different from that of a woman in a heterosexual relationship. Even if he had the status of a Prince of the Dong Lang Empire, he was a bottom when he was in the bed, and when he rode the horse with Zhu Ge, he was also the one sitting at the front.
Sure enough, his position was no different from that of a Princess.
