You should say how to get some of those. For example, in some cases its too much trial and error, like choosing to be top or bottom with Razzi. Not to mention I have yet to get any close to Yoshi's demise...

I do plan on doing some walkthroughs, and now that the writing is pretty much done, I should have time to do them.
(SPOILER)
Yoshi's Demise and Yoshi In the Middle can be found the same way... You choose the Kol route, then avoid intimacy with him. Do NOT kiss him and do NOT shower with him. When Nasir confronts you in the galley, you'll get a menu option that has three choices. One of them will continue on the Kol path, one will lead you to Yoshi's Demise, and one will lead you to Yoshi In The Middle.
For topping Razzi, you should tell him you love him when that option comes up, and also have sex with him in Chapter 6, which will trigger the Top option in Chapter 10.
