Matziv, I am not required to get married. I am not obligated in pru urevu. Why should I get married?
Not really true. There is a concept/mitzva of Sheves Yitzra, that all people should populate the world (see BB 13a (IIRC) by a half slave, and other gemaros as well).
I’m surprised that no one has said they feel incomplete without a partner in life.
