Don't call yourself a "father" court will try to use that against you, don't sign anything, it takes two to make a kid if she wants to go thur with it and not you, get a lawyer and make sure that it's clear you want no part of that child's life. Don't get stuck with child support for a kid you would have vacuumed up anyways. Also do not share your blood type with the mother because if for some reason that kid needs an organ later on down the road or whatever they will try to guilt trip you. Best is just to have one night stands and get a hotel so they never know where you live......can't force someone to sign parental rights if you don't know who they are.
