I'm currently going through puberty, but it seems like I have a problem. it doesn't matter how much I talk to someone who people say is attractive, I don't get attracted emotionally. This worries me because the Bible wants me to get married and have children, but I don't want to marry someone I don't love. Will it change, or will I go through life asexual? I ask God to help me be more attracted to females but I'm in the same predicament.
