I already try to chase girls like Tiger as it is right now, so I would probably continue to do so on a bigger scale if I became a millionaire haha. But I would have no problem giving that life up instantly if I find a woman that I love like that.
50/50 chance of me spending it wisely, or blowing it all off completely. If I do waste it, it'd probably because of traveling, gambling and bad investment. Not on women....well, not thousands and millions anyway.
