I'd rather chop my nuts off than have kids

Much rather have a dog.
Men don't have a biological clock - they can father children until the moment they die. You may have given yourself a psychological clock because you feel the need to conform to society's norms. You don't need to - there's no rush. You could father a child at the age of 110 (if you live that long)
Women on the other hand have a finate number of eggs. You produce 5 million sperm all day every day
Instead of rushing to have kids, you should first spend time looking for someone you like enough to spend your life raising kids with.
