Single dad with custodial custody here. I don't want to bring others into their life, and make either person feel obligated to play the role, or set my child up for disappointment or an abandonment issue if the relationship doesn't work (and that chance is very great). Personally I have learned to control my base sexual urges for the greater good of my child's future, and honestly after the first two years it became a lot easier .I'm at 6 years, no relationship or sex at the moment. I would feel like a failed parent with no self control if my kid got hurt because of my selfish, controllable desires.

I don't have the time, money, or energy to invest in a modern western woman, and too be honest it's not worth it even if you could. I invest everything I have into my child and I's future. I'm not saying you couldn't make it happen, or that you shouldn't look for someone, but at the end of the day your child needs your love, and tbh a chance at a platonic family in today's climate is next to zero, and is already not a reality.

Given there is barely any government or local groups for single fathers out there make it even harder, but it tests your resolve. That's just my two cents.
