Don't do it. It sounds good to your horny cum filled brain, but it isn't as good as it's cracked up to be. Get a life first.
First, if you're not going to college go get a job. Might as well work 40-60 hours, get two jobs if you need to. That can be put into investing, renting a cheap apartment, whatever. Also put some aside for diapers and shit. Once you're out of your parents house, then do what you want to do, and don't let your fuckin family or friends find out.
