I think it is super important to have someone in your life that you look up to and respect spiritually, and someone in your life who you are an example to. This world is a crazy place, and it is good to have someone to go to for prayer, wisdom and questions regarding decisions who is of the same gender and who you respect and trust. Ultimately God is the best One to go to, but it's good to have an earthly example that God can use to speak into your life.
It is a great opportunity to be used in someone else's life as well. It is such a blessing to know that God is using your experiences to help shape the life of someone else. I wouldn't go looking for this person whom you can "train". But instead, ask God who knows the perfect match. You might not have someone like this in your life all the time- at least that you know of. God uses us all the time without our knowledge. It is amazing when someone comes up to you and tells you how blessed they are by you! It catches you off guard, and blesses you substantially- especially when you didn't know you had such an impact on that person!
