It's really about how you get your rocks off. There is no wrong answer here, depending on what turns on the tickler and ticklee AND how they both associate --- or dissociate -- tickling with intercourse. I lean toward separating the two, mainly because tickling is about a steady stream of pleasure/torment, while climaxing is really about surging up a mountain, then falling off it, so the dynamics really don't jibe, for me at least. That said --- I'm very stimulated with a woman getting wet while being tickled, on any body part, through the mere physicality of the tickling literally turning her on sexually.
