My bf and I are just a new couple and are currently doing long distance. He’s a working man that’s why it is common for his nails to get some dirt under them which kinda bothers me as a clean freak and a health student. My bf is a little sensitive to physical criticism because he was bullied a lot as a child and I understand because I was too. I want to bring it up without triggering anything negative in him because he can get a little insecure sometimes and I don’t want him to feel that way. Thank you very much.
