How many people is it possible to sleep (have sex) with in an entire lifetime?

I'm actually speaking for both men and women and how many people both the man and the women can sleep with. And for all of you mathematicians out there: if it is possible to spend your ENTIRE life as an absolute and undeniable slut, how many people can a man sleep with over an entire lifetime? and a woman as well? Starting at puberty when the sex hormones and organs start kicking in..
