do it man! I know how you feel, and telling him may seem like a big deal but trust me it can be so simple, and much fun! Just make out like he already knows your gay and tell him all about the guy you've got the heat for. Then tell him you want to have a same sex marriage and have surrogate children with a lesbien couple. Shock factor will definately weigh in in your favour.

Seriously though, be true to yourself and tell him you dont like girls but not to stress about it because you've got it under control. You know what you want and its your life, so tell him to but out. Its not really any of his business but he does deserve to know all the same.

Anyway, if all else fails tell him its genetic so it must be his fault. hahaha!

If he kicks you out get a real daddy who'll love you and treat you right.

Be proud and be strong.
