Another thing, there is no guarantee you will feel a connection with your kid, especially as a male. It took about a month and a half before I felt a connection and it was incredibly hard to get up late at night with a screaming baby that meant nothing to me. There were times I wanted to just open the window and throw him out. From the reading I did, there are men who have not even felt a connection after 5 years. Could you imagine having to take care of a child who you feel nothing for? That doesn't sound like happiness to me.
Like others have said, it looks like you are looking more so for a pet than a child. Though, if you would be up for it I am sure there are mentoring programs (such as Big Brothers Big Sisters program) where you could have a meaningful impact on a child's life with the ability to walk away if it isn't for you.
