Obviously, no individual can speak for such a large and diverse group with any real authority; but here are some of my thoughts:
1.) What do you guys find so attractive about panties, like I get the what's under it, but what really fascinates you about them?
-They aren't a huge fascination for me, but they can certainly add a certain allure when a sexy young lady is wearing a skimpy pair of panties either by themselves or along with some cfm heels and maybe some sexy lingerie. It's also pretty sexy when a lady uses a worn pair of panties to gag her partner.
2.) On top of the previous question what's the larger appeal to feminization or sissification?
-Honestly, this isn't one of my kinks; but I think the appeal lies with the taboo. The idea that social norms dictate that men should not appear feminine or wear women's clothes makes it appealing for some. I also think that it plays into a humiliation kink that some men have (also not my thing).
3.) I get the whole pain is pleasure, but what is the appeal of ball busting for men?
-I think there is room for some nuance here. Personally, I enjoy having mine tied and/or squeezed sometimes. Even some light to moderate impact play can be fun; but that's as far as I'm willing to go; and it is mainly a masochistic pain can be pleasure thing for me. There is also a power exchange aspect that I love; and some toys, like ball presses for example, are genuinely scary, and fear play can be sexy if you trust your partner.
There is also something sexy (and this really is still related to the power exchange) about offering the most sensitive parts of one's anatomy to a dominant woman (who one trusts) who looks sexy in an evil way.
The part of it that I don't really understand is the extreme side of it. Full force kicks or punches, trampling, needles, etcetera. Those sorts of activities are simply too much for me, and IMO they become a turn-off.
4.) If you've managed, how much more pleasurable is a prostate orgasm over a normal one?
-I've managed once, and over-all I found it more frustrating than pleasurable. It is very different, and there is a lot of pleasure involved; I simply didn't find it satisfying at all. It felt more like a ruined orgasm than a climax to me.
5.) finally, when it comes to edging and climaxing, is there a limit to how far you can push yourself with it, or is it all depending on the person?
-The short answer is that I think it does depend on the person. But I think it can also depend on the person's mood and a variety of other factors both mental and physiological. I've heard it said the the brain is our most important sex organ, and I think that is true to a large extent.
I am a switch, and if I'm not in a submissive mood, I generally don't have the desire or self discipline to edge multiple times without climaxing. At other times, I've edged literally hundreds of times and enjoyed several months of orgasm denial at a time.
If you are asking how many times someone can edge in a session, that can also vary. I've experienced sessions where I've hit my first edge in a couple minutes and returned over and over, sometimes holding an edge for 5 minutes or more. Other times, I've found it to be a challenge to edge more than two or three times in a session.
I believe that there are a variety of variables that affect this. How much sleep have I gotten recently? Have I been eating well? Am I well hydrated? Am I stressed about something? How long has it been since my last release? Have I become bored with the scenario or the session? All of these variables and more can play a role in the way I respond to a session, and I think that's true for a lot of people regardless of gender.
I hope that helped.
