Am I the only one?

To give some context, I have been permanently locked since January 1. The only time I am released is for cleaning and supervised breaks. The only way I am allowed to cum is her fingers, toys or strapon. She let her lover take me only once, but I’m to cum from anal only. My proposed discussion is that the longer I’m locked the more I feel myself gravitating towards penis. Not necessarily that I find men attractive but I just want fucked to feel pleasure, does anyone else have the same feelings after being locked a prolonged time?
