As a young man, I too experienced something similar and it’s stuck with me my entire life. I’ve worked with multiple grief/trauma Counsellors to no avail. The day I heard my Grandpa say penis will forever be engrained in my memory. I’m starting to shake uncontrollably and tear up writing this. I hope this comment is somewhat comforting for other who’ve experienced something similar. Hopefully they find solace in knowing that other people have in fact heard their grandpa say penis at a young age.
