I have personally known three people my own age who became priests, plus a few more who became pastors in Protestant denominations.
The three young men I knew who became priests all had social difficulties beforehand. The single thing all of them had in common was difficulty forming strong friendships with other guys and difficulty in dealing with girls and women, both socially and sexually.
It's a very, very small sample, of course. Those three found comfort in the rituals and organized focus of the Catholic Church when they were in high school. They went on to find vocations within the RCC. I lost touch with all three of them once that happened, so I have no idea how they are doing now, over 50 years later. They aren't on any of the social media venues, nor do they involve themselves with our school's alumni association or show up at any reunions.
It is as though they dropped off the face of the earth, with regard to people who knew them earlier. I hope their lives have been rewarding for them, and satisfactory, but I have no way of knowing. I moved away from my home town at age 18, so I don't have a lot of regular contact with others who knew them. I am involved with my alumni groups on Facebook, but nobody seems to know what became of them there, either.
I remain curious, but have no real way to learn anything more.
