I still disagree with the first post question, and not because I misunderstand it:
" So do I:
1) Selfishly tell my significant other to get circumcised [I'm aware of pros/cons], portray that I don't accept everything about him, ultimately making him feel worthless just so I can be sexually/physically attracted to him. And to add on, he admitted he's not 100% sure about doing it, but he offered if I preferred it.
Or 2) Tell him not to, which is basically lying to myself to spare his feelings, and stay uninterested to him sexually."
I maintain it is not appropriate for you to tell him to fix or not fix his penis.
I understand you disagree with my comment on your not being clear on personal boundaries, but that is my opinion.
It remains my opinion, whether or not you changed your mind about the aesthetics (etc) issue.
