Is "no" really that hard to understand?

There must be some weird translation that happens to my words in the air just outside my mouth. For some reason when I say "no" it's missed or something. Why can't "no" be "no" and left at that? Is it really that hard? Or even when I say it several times...how is it still not heard?! Maybe it's just a guy thing. Maybe guys hear my "no" as more of a "lay it on me". I just don't get it. It makes me sick and I'm so tired of that continuing to happen to me. If I say "no", I freakin mean it!! That's why I said it to begin with!! If my "no" can't be respected, put your hands in your pockets and walk away from me and don't plan on coming back. I'm going to give respect. I would like that in return. Thank you.
