I do not understand these situations. When I say "No" to homosexuality, men want to sodomize me. When I say "No" to trolling, others start trolling. When I say "No" to sex, others want me to have sex with them. When I say "No" to stalking, others stalk. Many people think that saying "No" to certain things is like begging for it. Not true. It is NOT like begging for it. Saying "No" to them really means "forbidding it; denying it; shutting it down; you want nothing to do with it". I looked up on Dictionary.com and found the definition for "No" and it means

These are the definitions for "No", so when I say "No" to certain things, others have the nerve to do it anyway? They don't respect our wishes or rights. Violating them will get them into trouble. I do not see the logic behind thinking saying "No" to certain things is like begging for it. It doesn't make any sense. What makes them think that saying "No" to those things is like begging for it? I cannot comprehend.
When I say "No" to certain things, then they should stop right there. *snaps fingers once* I know what "No" really means. See the definition in Dictionary.com or the one above for more details. Read that clearly. Saying "No" to certain things is NOT like begging for it. Reality check.

Begging is like wanting it, and wanting it is like saying "Yes" to it. "No" is the complete opposite. When I say "No" to certain things, our wishes are ought to be respected. We have reasons to say "No" to certain things.
