One way to approach sex scenes is pondering the limitations of the media. Games are visual and we can't deliver emotions like longing, love, lust and other things, like touch. We can't make long descriptions of them, games are not books so we have visual presentation, voice acting, music for mood.
Sure we can. Plenty of games (Planescape: Torment, for instance) use text quite effectively to depict emotions/senses/etc.

In the other hand, how much is tasteful to show? Where is the point where visual presentation turns from portraying emotions and human interaction to exploitation or porn?
I think the main issue is this: our visual media (print media are a little better at this) tend not to depict the sort of sex that people actually have in the real world. You've got the hollywood sort of sex and the porn sort of sex, both of which are equally unrelated to IRL sex. Mass Effect is clearly working in the hollywood tradition here, and is doing so in a particulary awkward manner.
