I assume it's not exactly your thing but do you know any good artists who draw non straight porn? gay porn?

Oh sure. 

Also here’s a link to a list I made of some of my favorite porn comic artists

Hamlet Machine’s Starfighter is AMAZING. sci fi gay comics with lots of sex scenes. 

THE MASSIVE, is a really great gay porn manga anthology that Fantagraphics printed in English. my favorite stuff in it is by Tagame & Jiraiya

The Jiraiya story is about a caveman who rides a bear who doesn’t understand why he can’t have a baby, but only wants to have sex with dudes.

There’s ONTA’s whole hardblush crew, he draws really feminine furry dudes (and was in the ISLAND anthology I edit with Emma Rios)

Michael Vega AKA Miu does really good furry stuff too. (& draws both gay , straight and lady-gay comics)  And Daria McGrain too  

NERO O'REILLY does some great furry stuff too.

MAKA MAKA is a reallly sweet lesbian manga by kishi torajiro (here)  (I just assumed you meant gay dudes – but maybe this works too) 

And Zasha did a sexy lady cop comic.

tanuma yuuichirou draws all over the map. he does some nice chubby dude porn. 

Also GET YOUR MAN is a fun Canadian Mountie web comic (here) 

There’s APPOLO POP (here) 

I’m probably leaving out a million, but hopefully there’s some in there you haven’t seen.
