Ok, I wasn't exactly specific here. Over the course of about 100 pages, he ends up in a mythical realm with some ultrasexual fairy queen seductress type, and she teaches him all about sex. AAAAALLLLL ABOUT IT. Not graphically; it's just assumed in the pages. But pretty much he hangs out in this faerie realm for a long time having lots of sex. And getting a few other things done, but mostly the sexings.
