Well, I don't know how much I needed my dad in my life, but it was around the same time as you - almost 11 years ago. I really don't know if he would have accepted me, he seemed nice but I don't know. My mom though is really hardworking and a great person so I'm just glad that I have her as a parent.

I'm not in the same situation; my biological father walked out of our lives when i was 12 but I already had a good stepfather then.
The biggest effect I would expect would be that you haven't had a father figure. You may have replaced him with another male role model though.
My fiancee has four kids from her previous marriage. The second-oldest son tends to look to the oldest son as a role model. In this case it's not a good thing because the oldest is self-centered and nearly incapable of empathy. Since I've been in the picture I've been trying to provide a good example for all of the boys. I think it's rubbed off somewhat.
If you're worried about not knowing what a man should do in a given situation, you might consider looking for a mentor, an older man that you can respect and look up to.
