Can anyone tell me who are the male love interests and how to get to their routes?
Hey PaleAngel! There's an ingame walkthrough (press 'w' to bring it up) and all gay & bi choices are written in pink. That should help you see the many secondary male relationships you can get.
The walkthrough doesn't extend to this update yet - but you'll find the Primary Love Interest choice right at the end. The male options are Sam and Cole :)
