Harem Overlord: I ALWAYS Finish Quick!

Summary:

Raised on earth to be the ultimate playboy, Ryan finds himself traversing into another world, being the only male on the planet able to cultivate.
Men are used as little more than servants, but a select few are born with the power to be enhancers.
Enhancers seed has special properties that help cultivators rise in levels, but it looks like all the men on this planet have severe erectile dysfunction…
With Ryan’s devilishly good looks and skills, will his previous experience being a one-pump chump be enough take the world by storm? Or will his end be as fast as he is and come to a finish prematurely?
