Yes...
However, if the experience in Knox The Hatter's marital bed is any indication, for most of you out there, the experience would be disappointing. I tickle Mrs Knox during sex, however, here's an instance where she's not screaming with laughter, herking and jerking, as she usually is. The sensations serve to intensify the orgasmic experience when done correctly (no spiderfingers or anything like that; gentle glides with index fingers are the key). She thinks it's a wonderful thing. However, it's also hard to do when YOU'RE in the throws of ecstasy.
Otherwise, conventional tickling, she tells me often, distracts from her sexual experience, and can even ruin it. I can tell you that it is indeed a distraction ("here"-smiling-"have a taste of your own medicine!"). I have friends here on the board who tell me that they can't do without conventional tickling during sex, that it makes for multiple orgasms, and that's incredibly wonderful in and of itself...however, I think that with most people, it resembles my own experience. Your mission, should you choose to accept it, is to go out and find a partner like the just described. Bueno suerte.
Whatever turns out to work best for you...
