I don't want to get married because I know how hypergamous women are and I am definitely not an alpha, neither physically (slightly below average stature, small frame) nor behaviorally or economically so there's little chance to find a woman sincerely attracted to me and I don't want to be a beta provider. On the other hand I wouldn't mind having kids so I was considering the idea of finding a woman willing to procreate with my semen. Im kind of advantaged since in my country the local laws don't allow single women to resort to sperm donation. I guess there might be a single woman, maybe a lesbian, not willing to spend an unordinated amount of money in fertility trips outside of the country and accepting to settle for a beta donor like me as I am not that bad after all. I would contribute financially to rise the kids and supervise their education granted that the mother would be a decent person and not a crazy bitch.
I don't know how to call this thing, it's not surrogacy though.
