I just know about Sensitive Pornograph and the Legend of the Blue Wolves, is there another one?
Not that I can think of. The only other yaoi I know of (anime wise), are either all censored, or don't have any sex scenes in them at all.
I haven't seen any of the yaoi that are the manga but voiced, though, but I believe these two are the only ones.
Sorry for the inconvenience.
If i remember correctly, Haru wo Daiteita--or rather one version of it that was provided by a forumer in the BL download section--is uncensored. The OVA itself does not have much in the way of full-frontal nudity so one cannot expect much but certain scenes from this version shows much more than the previously available ones so check out this title. Other than that, I highly doubt that the BL titles that comes to mind---other than the ones that have been mentioned--are uncensored.
There is also "new version" of Winter cicada made by the same person (HWDI). Not full movie but the most important part
Oh, boy, I don't remember now... I think I saw these anime edits at Youka Nitta's livejournal comm?

there is actually very very few that have not be edited or censored...many were made at a time when boyXboy was super taboo ....so the few that did make to market(this is for anime series/ova) had been altered from there manga counter parts to show almost nothing in the way of romantic interludes .. aka ..no nakeness/hot kissing or very little showing only a bit here and there and no frontals ever... (remember level C .... invisible Penis ..) it was very much the norm to do that kind of thing ....still is mostly...which is kinda sad ...
If you like BL games, the English versions of Enzai: Falsely Accused and Absolute Obedience are uncensored (though the urine was removed from some of the urolagnia scenes in Enzai, though the dialogue/description and sound effects were kept). However, sex scenes in manga/anime are pretty much always censored to some degree (manga usually less than anime) because Japan has laws about naked penises (i.e. you can't show them - same goes for pubic hair). Of course, people get around this by sticking white/black boxes over parts of the penis, or showing every bulging vein through a condom etc. all of which are technically legal - obeying the letter of the law rather than the spirit XD
