COWARDS! DAMN, DIRTY COWARDS! This manga has been listed by 2,000+ users, but nobody ever wrote a review until now. Coincidence? Nope, I think a lot y'all are too embarassed and immature to discuss this series like proper adults. Pathetic! Premise: There is a condition that makes men cum diamonds at the cost of their lifespan, while also secreting attracting pheromones. Our MC has this condition. Positives: This series combines the over the top scenario's and pretend-seriousness of something like "World's End Harem" with the light-hearted silliness of a sex comedy, think American Pie. There are a lot of funny lines and absurd scenes depicted skillfully bya experienced mangaka.

Negatives: Can get repetitive sometimes, characters are not anything special.

Meme Potential: Tons of it, if this had an anime you would be seeing screencaps and memes of it everywhere.

tl;dr It's pretty good.
