WOW those sex scenes are...detailed and well done.

I have a question. Does anyone think that the sex scenes between Ryder and any of the alien characters comes off as 'too casual'? Like Ryder and one of the aliens decides to have sex and bam. They just go for it, no questions, concerns or even kinky stuff brought up.

Take the sex scene with Vetra for example. I remember thinking about what sex with a Turian would be like and the potential risks that were involved since their skin is very tough and pointy. Since her sex scene is one of the many fade-to-black sequences, I kept wondering to myself. Why not actually use this sequence to build a bit of character? Like showing Vetra being nervous about how she interacts with Ryder and vice versa. Nothing too explicit has to be stated or shown, but giving both of these characters a moment where they try to figure out the differences between them would have made for one heck of sweet and tender moment that Mass Effect hasn't really explored in the past. Now of course you can mention Liara and Peebee with the Asari bonding, but that's too easy and even in both cases doesn't really go anywhere.

Eh, not really since then that excludes certain types of stories being told on both sides. For the majority of romances that does works, and really you just explained Group C in my post. 

Well, to give an example of each case:
A romance that requires sex would be something like Morrigan's since it involves conceiving a child or a character who enters a casual sexual relationship which then deepens into a real one.
A romance that requires no sex would be something like an asexual character or a person who for some reason like religion or culture abstains until marriage. 

While I appreciated what little moments that romance gave these two characters when it came to their intimate relationship, it still felt like it was playing it safe. Why not have this "how to please" conversation with Jaal himself with multiple choice responses? And maybe have Sara ask how she can *clears throat* please him? Gosh, this is so awkward talking like this on an online forum.

Basically, yes. What we've got is ok, but this installment needed to do more. 

When you get down to it, do any romances make it to the third date before sexitimes ensues?

Vetra involves helping her sister, going mountain climbing and having dinner. Three dates before they do the nasty!

Eh. But not good as Witcher though.

Keep on dreaming.
