both depending on the mood and situation. dirty talk is by far the best tho. nothing hotter than 2 people in to making each other hot and horny just by words.
I talk to encourage him to talk. Maybe it's a sex game he plays - but his voice is insanely sexy yet he tries to stay quiet sometimes, only to spur me on.
Both are good. Talk can be fun, dirty and/or sensual...or good for feedback. But sometimes talking isn't necessary...just the sounds of bodies coming together. And moans...and sighs...and grunts...and whimpers.
we discuss the sports scores, who we think will win football games this weekend and sometimes we talk about the weather in places we will be traveling to, in the near future
