Naah, if the other bears were lesbian, the wishing bear would think they are performing just for him.
Trust me, I've had str8 roommates, that just go crazy for Lesbian Porn.
The typical thought is "They are just doing each other because I'm not there yet."
They don't get it even when they are told, "You are not only not essential for the sexual pleasure of a woman, you wouldn't be able to do anything to help, even if you were there!"
Sometimes I wish I would have hid a camera somewhere, because he would constantly brag about his endowment, but wouldn't show it off, even when he was falling down drunk. Poor, insecure str8 boy.
