Most Helpful Guy
I am almost 24 and in a year, I will be more than ready to start looking for someone to settle down with. I would say it is no problem at your age as you can date older guys who are ready to settle down, I think I am in the minority a bit of 23-24 year old guys looking to settle down.
If by donor you mean sperm, it would greatly hurt your chances of finding a guy. I want MY child, I am young and healthy enough for it. the only time I would go for a donor would be if one of us were infertal, but honestly I would still rather adopt so it is not just one of ours.
