Well, it's all over the map!
You can check the Field Reports Board on the forum and look at who's posting lay reports, and how many:
Guys don't post all their lays, of course. Some guys only post a handful of their lays. But you'll see some who post quite a few in a given year.
Some guys only sleep with a few girls a year, and that's enough for them. Some guys sleep with a few new girls in quick succession, then meet an awesome one and get into a relationship. You'll find this happens with lots of guys, actually... I plan to do an article on this trend, in fact. A guy starts to hit a new peak, and then boom - into a relationship he goes! Very common.
You certainly can put up big numbers in a hurry. But you need drive, hustle, and skill to do this - it takes work.
