I’m a happily married man. If you ask me to have sex with you, I’ll politely and, as gently as possible, refuse. I don’t doubt a part of me would be flattered by the attention. I would not be offended.
If you refused to accept my answer, I might be irritated and less gentle, but I still would not be offended.
I am trying to understand the mentality that says a request for sex is offensive. It makes no sense to me. How else is someone who wants sex ever going to find out?
