<human>: Can you give me the gist of the text in a nutshell?

Let me start out by saying, I'm a 28 year old male. I'm balding just slightly, quite successful, but the only thing that looks good on my body anymore is my face. I tend to have a gravitational pull on friendships with the other sex often, and I attribute it to my flirtatious attitude and kind demeanor. 

So this evening, yes this very one, I was offered sex in a curious fashion. I am married, and I have never really been put in a situation like this. The lady that offered was a close friend of mine. She has an amazing personality and I didn't even realize what she was doing. She and I were talking about her most recent relationship and she went into a conversation about desiring a FWB. What I didn't realize is that she was referring to me. As a married man, I have never had this problem, or had someone even approach the topic like that. I drove home only to receive a txt stating that her offer was obviously declined. Apparently my "I need to get fucked" radar has stopped working. Or perhaps what little morals I have left are finally playing a role in my life.
<bot>: Friend wanted a FWB relationship with me, a married man in a sexually lacking marriage. Walked away and was told of my mistake immediately.
