For me it is turn-off, in case the Vers wants me to be the top, which is something so ridiculous I can't even imagine it, let alone actually doing it. I bottom only with my silly dicklet caged 24/7. That's how I was designed and I feel that going against it would be a cardinal crime against Father Nature and huge disrespect to all real Tops/Doms, who were born to penatrate an breed.
On the other hand, Verses, who are at the moment in their breeding mode are more than welcome to use my boi-pussy for their pleasure. For they as well might have fine top-like cocks and that's all that matter to me.
To summ it up, the "category" a man falls in, doesn't matter really. Technics, means and actions he intents to use/perform on me are crucial.
