It's fantasy. Feeling obligated and forced turns some people on. I'm with you, I don't find it particularly exciting and it can become off-putting quickly, as you expressed in your comment. The fact is, when I have protested during sex that I do not want to do that, or anything I'm not into, I've never had a problem with the guy getting too hostile or demanding. I say, calmly and clearly, that I'm not going to do that and the vast majority of the time, he immediately acquiesces and moves on to something else. As I have not made a big deal about it, but have stated plainly that it is not going to happen, he realizes quickly that pushing the issue will only ruin the energy we do agree on. Only once has a guy been unwilling to compromise and we were at a bathhouse, so leaving him was as easy as picking up my towel and opening the door. To be honest, I don't think he had even realized exactly what was going on until I was gone.
One time, I was playing with a guy who slapped me around a bit while I was kneeling in front of him. It was very hot and really fun, for sure. He bent down and whispered something kinky in my ear, but as he rose and turned his body, he caught my head with his elbow. It wasn't hard and it didn't hurt at all, but he stopped and his whole demeanor changed. He asked, "are you ok?" I quickly and easily assured him that I was, because it was no big deal at all, and he looked me right in the eye for a half moment; we checked in with each other and everything was good. Then he gave me a slap on the face and told me to suck his cock. So hot!
When I do ATM, or cocksucking, or kneeling, or grovelling, or begging, it is because I enjoy it. If I didn't, I wouldn't -- and I'd be like the vast majority of the human population! haha That said, dirty talk is fun and exciting, even if it isn't literally true. It's "just a game," as they say, but if you're going to play the game, play the game; you get out of it what you put into it. For many guys on here, talking about superiority and inferiority, duties, dominance and force, in ways that are fairly over the top is a huge turn-on. As that kind of talk is annoying to us, we just disregard it and enjoy the many other interactions and fantasies available.
The way I see it, no one who has made comments like the one's we have issues with is in a position to force us to do anything they're talking about, and they never will be. My goal is to cultivate people who like, shall we say, the same coin as I do, but they prefer the opposite side.
