Some manga's I have read I think I shouldn't add to the favorites but keep it to a blog.
For example the comedy/romance/ecchi ones that have an overload of "mature scenes" but its almost to the point of stupidity. It is way out there but its also funny since they are failing at trying to get imitate.

Such as
iinari Princess
its about a guy who catches a princess farting on a rooftop and well becomes her sex servant/husband to be.
Or this one that is comedy and more soft hearted romance:

Nishiki-kun no Nasugamama
The girl describes the relationship as her as a hamster and the guy being a snake. This one is more so shojo, its cute romance but it's the "you belong to me" scenario as well.

Un ChocoholicThis one shot was actually sweet in its dominant way, wish it was longer series!it revolves around a chocolate that was left out. Its cute.
Antique Wish e Youkoso
Then there is this one shot romance, a store that grants wishes to it's customers.
-------------------------------

Then the wtf is going on to this guy who has become a sex slave but ends up in some family scandal. Lots of mature here due to neglect & loss of a parent leading to the "high life"
Velvet kiss
Then the series of the erotic fairy tales, its silly and light mature, not the best story warp, but if you are bored its fun.

EFT: Red Riding Hood
The family of red is criminal mobsters, the wolf is enchanted with powers.
Minor nosebleed reads with silly grins!
