I Don't Get It, What's the Point of Striptease?

Call me weird, but I've never been able to get my head around what's meant to be the big deal about striptease. What's it for? And who's it supposed to appeal to? Back when I was a kid, I assumed it was this really 'adult' thing, but when I got to be an adult myself I just thought the whole idea was stupid, partly because of the 'You can look but you can't touch' concept rendering the whole thing pointless and partly because you'd surely need to be an overgrown 12-year-old boy in order to derive any sort of a buzz from it. Maybe striptease was arousing back in the 1940s or the 1890s or whenever, but in my lifetime it just makes no sense. And people PAY to watch it, can you believe? They pay to watch a few quick flashes of something which they're not allowed to touch or even get too near to. It seems to me like it must be all for the dancer's benefit, because for the life of me I can't see what the audience gets out of it. Anyone?
