That's the key, and the problem when you lose focus on the main story. Supposedly the next update will have Alex/Tasha stuff, but it's going to be really hard to come back from this.
Eh, honestly blue balling doesn't have to be a thing with the main LI either, at least not to the degree seen in a lot of games on this site. After a while things simply stop being plausible. Sex with the LI does not have to be the end of the story at all, it can be part of the introduction, somewhere in first act, in the middle, anywhere really.
