No idea why, but when I play on myself or even I act as a patient, I like to have my legs covered with white socks, and even head and arms. The fact to be fully naked, and perfectly shaved, only on the torso from neck to penis, it make me more exited.
If I play as doctor with a female patient, I like if she wear white underclotes, maybe with monouse panties or even something I can cut with scissors while undressing her.
Sorry for english, but I dont speak german unfortunately
