Name changed for this one. I have a lovely son, age 4, about to go to school. I don't want a relationship. I've been single since he was born and absolutely love being a lone parent. I'm good financially, I live in a lovely house which I've made my own, have a good job, and lots of family support. I love my life. I really, really would love another child, possibly two but not thought too far ahead yet. I've been toying with the idea of sperm donation. I'd love to do it, but the only thing stopping me is the worry that a child could grow up to be affected by the way they were conceived. Is it ethical? Is it really OK to do this? I'm so torn. I want another biological child but don't want to if they're going to potentially be traumatised by the mere fact that they exist. It sounds awfully dramatic but I feel like a lot of people don't think about this side of things. Does anyone have an opinion on it?
