Personally, I find it annoying and a turnoff. Sayng/yelling "Fuck" is fine and good with me (hey, that's what they're doing anyway), but there's just something about "Shit" that just throws it all off. It strikes me as a negative exclamation, not as a "Yeah I'm loving this" expression...not to mention what 'shit' is. It's not something I want to think of when watching porn...however some people are into that kind of freaky stuff. Ewww.. A perfectly good Jenna Presley scene was just ruined for me because she kept saying it and so did the guy.
