Hello backtogiality: I see this is your first post here on PC. Welcome to Psych Central.

With regard to your concerns about hurting children, there's an article in Psych Central's archives you might take a look at. Here's a link:

You mentioned thinking you might be asexual. There is an asexuality forum website you might check out:

At the end of your post you asked if anyone had any advice or insights as to what you might have. I think the best advice I could offer would be to see a psychologist or mental health therapist regarding what you're experiencing. The majority of us, here on PC, are consumers of mental health services not mental health professionals. So any insights we might have regarding what's going on with you would be nothing more than a guess based on limited information. Seeking the services of a mental health professional is the way to really begin to understand what you're struggling with. Nevertheless... there is a lot of support that can be available here. So I hope you find PC to be of benefit.
