That's because /h/ thinks it's too weird, and /d/ thinks it's too normal. I deal in all stages of breeding, so I've got some impreg to go with my preg gig on /d/.
Believe me, if the market for it was here, I'd post it on /h/. But until a determination is made as to where preg stands, I'll keep it on /d/ like a good boy...
There's a preg thread just gettin started over on /d/ right now, we'd love to have ya join us.
I've got 2 manga pages though the 2nd might be a bit...odd.
