"Household life is crowded and dusty; the homeless life is wide open. It is not easy while living in a home, to lead the holy life utterly perfect and pure as a polished shell."
We also find, in
MN 101, the following:
"Suppose that a man is in love with a woman, his mind ensnared with fierce desire, fierce passion. He sees her standing with another man, chatting, joking, & laughing. What do you think, monks: As he sees her standing with another man, chatting, joking, & laughing, would sorrow, lamentation, pain, distress, & despair arise in him?"
"Yes, lord. Why is that? Because he is in love with her, his mind ensnared with fierce desire, fierce passion..."
"Now suppose the thought were to occur to him, 'I am in love with this woman, my mind ensnared with fierce desire, fierce passion. When I see her standing with another man, chatting, joking, & laughing, then sorrow, lamentation, pain, distress, & despair arise within me. Why don't I abandon my desire & passion for that woman?' So he abandons his desire & passion for that woman, and afterwards sees her standing with another man, chatting, joking, & laughing. What do you think, monks: As he sees her standing with another man, chatting, joking, & laughing, would sorrow, lamentation, pain, distress, & despair arise in him?"
"No, lord. Why is that? He is dispassionate toward that woman..."
Additionally, I'm having trouble finding a site cite (!), but Anguttara Nikaya I someplace remarks that the aggregates of a woman, for a man, are the single thing that persistently obsesses the mind most. For women, it is aggregates associated with men. For bisexuals and homosexuals, the personally appropriate reading should be inferred.
Nomosexual is the way to go!
