Yeah, tickling is a constant in my mind during wake hours, and some great dreams when i'm asleep as well. My gf and I have kids (great ones at that) and its very probable that tickling played a huge role in it. Her work set her up in a five star hotel with indoor/outdoor pools, hottubs, great beds, couches, you name it. There was play, there was sex, there was..well use your imagination.. We very possibly conceived our kids as a result of being outrageously passionate, and playful. And before the judgers pass judgement; I have no regrets. Sometimes if i'm busy, or agitated tickling is the last thing I might want to do, but like a mouse in the corner cabinet it's still there..
