I do hard kinks, rough at minimum. Soft or vanilla don't usually interest me.
Don't be upset if I don't respond. I'm gonna be frank, if I'm not interested then I generally won't reply (or I'm just not at my computer at the moment). It doesn't mean I hate you or anything. Although, I will say something if we've already started and I'm just not feeling it, or if you decided to make an impressive IC approach (which awesome, but I don't recommend it since they require effort and are hit or miss).
Don't be afraid of approaching me with TOO hard a kink. I'm into a lot of things, and the very few things I'm not into, worst I can say is no.
