I agree that some people would react negatively about rejecting sex like Miranda: "You want to say that you don't want my perfect body?" But Tali? The quarian with weak immune systems who can actually die of intimate contact with Shepard BEFORE the most important mission? This is nuts. Of all the things she should react understandibly and admit that this is indeed a bad time for risking her health plus Shepard's quarters are probably crawling with Cerberus bugs. And of all people her romance should've been purely platonic. Plus it's not like she can't feel pleasure through her suit...
And it's not about seeking romance in the game. Games, like movies, are stories. In these games I don't look for a virtual girlfriend, I look for a nice chemistry between characters. In the movies romance happens for a reason, It provides stakes, gives the protagonist some character etc. Same with these types of games.
On the other side, Tali's a 24 year old who grew up loving sappy romance flicks, but is still a virgin because she's stuck in a suit with shitty immune disorders. She's probably horny AF (as people of that age group naturally tend to be) and likely tired of getting her rocks off by ****** a piece of suit software at this point. She doesn't exactly react negatively when rejected, anyway, merely saying something like "*sigh* can't fault a girl for trying" then walks out, which honestly is much nicer than I would have put it if a dude had led me on for weeks/months, made me do all kinds of research and jump through hoops due to medical reasons to have a physical relationship, then rejected me anyway. She wants sex, so it makes perfect sense that she gives up on your Shep if he has the libido of a plant, and decides to look elsewhere where there might be someone more compatible with what she wants, like say the forward battery. ( and honestly, the whole "I could die" thing is so overblown for cheap drama to the point of being completely cheesy and laughably stupid, anyway. Like, you're worried about safe snu snu, but going on missions and getting goddamn shot multiple times is totally fine, idiot?)
Honestly, I'd hate it if characters didn't have a predefined attitude on what they want from a relationship. It seemed dumb in ME1 (especially with Ashley), and it'd be dumb with anyone else. Characters should act like people, not malleable drones for your ideal roleplaying experience (they already act far too much like that), and real people who want sex have needs. They aren't just going to be like "sure, I'll wait forever", they're going to start looking elsewhere if you aren't willing to give them what they want in a reasonable timeframe. Assuming otherwise is as self centered and offensive as a character who is defined as willfully abstinent due to religious/cultural reasons suddenly wanting to bang the PC (arguably moreso, because sex drive is innate and natural to everyone who doesn't have a biological disorder, and can't really be completely suppressed, whereas abstinence is a function of the superego that can be easily modified by a new worldview).
We're all animals, and most of us just wanna bang. If anything, it should happen sooner rather than later.
