Dog Lovers: do you prefer male dogs or female-spaded/nurtured or not ?

either gender i would own would be neutered ... my first dog was a neutered male and my current dog is a spayed female ... i think it is a necessity with females as i would never breed a dog and i would not want to deal with a dog going into heat ... and i would neuter a male because i am not insecurely attached to testicles ... the only male dog i have known to not be neutered, was a roamer around the neighourhood, would mark in people's homes, and was aggressive with other dogs ... the world is the way it is because of too much testosterone so if i can do my bit by neutering a male dog, i am all for it ... i am female ...
