I strongly agree that not knowing what is being put into your body is very fulfilling and good thing.
I had the privilege of being associated with the very thing you were talking about. I didn't know, of course it wasn't my body, but neither did my girlfriend. Seems a child was placed inside my girlfriend without her knowledge. There seemed to be some issues with her natural adult female cycle and she had a friend, who by the way had a similar experience, told her to get a child test or something. Not a PCR test, it was different, this wasn't shoved up your nose. This test said she had a child in her. It forced it's way out of her and now it runs around the house.
I have noticed and this should be a warning, that guys with girlfriends are targeted for this thing that somehow inserts a child into your girlfriend or wife. So you may want to get some security cameras or something. It's ok, these children can be fun, but that's after the all day all night crying thing. It has made me learn how to take care of myself. The child taught me that. SO this is a good thing like you said.
