What's it like to be a single gay father

I'm very curious what is it like to be a single gay parent. How did you have your babies, by surrogacy or adoption? How did you become a single parent?Because I'm so frustrated about the gay love/relationship. The emotional inferiority makes me never tried any relationship and now I feel I would I will be single forever. But I still want to have a family because I like kids and think I can be a good father. I watched a short documentary about a single gay father and his son's life. I think that would be my life goal although life could become tough. So I am quite curious about it....
