i'm looking for a hentai anime or manga about one of the following

1.a romance involving BDSM or bondage. not looking for mindbreak. either the two start fall in love and start, or a girl(or guy) falls in love over the course of a dom/sub relationship. blackmail is o.k. to start with, but couple must come together out of free will. male dom prefired. a good example is cleo patra and I, or in the borderline category nana to kaoru.

2. a romance that either starts with pregnancy or is about trying to get a girl pregnant. have yet to find a good example.

3. a mangaka/doujin maker, in a relationship with a someone who models for them or an assistant. examples: darling(very good) the first part of let's make an ero manga

4. hentai anime about two characters who have liked each other for a while but never told each other (nothing too girly). example: too many to count

5. two people with the same or similar fetishes that come together. (can be stacked with number one for two people into bondage). (cite fetish in recommendation).

6. love between master and slave (stack with number one for best results). example: fencer of minerva

site which one of the six in your recomendation

also for number 6. it can be matching fetishes. like exhibitionist girl who masturbates in a place where she might get caught and voyeuristic boy who secretly watches her.

Love Fencer of Minerva - hated the English voice cast.

Anyway, you might try Berry Ecstasy. It's not a

hollywood happy ending sort of manga, but it's definitely an interesting storyline. Sort of fits #5, I guess? They try several different things.

If you've ever thought or said "Nice Guys finish last" and really meant it, then you should probably read this LJ post by DivaLion. It's incredibly insightful whether you're male or female.

From a bumper sticker I like:
"If you're gonna ride my ass, at least pull my hair."

There's a hentai anime called Honoo no Haramase Tenkousei that could fit #2.
Ringetsu and Shin Ringetsu also fit #2.

Honoo no Haramase Tenkousei was good except for the fact it was weak in the romance. ringetsu passed
