Hopefully it will be fixed at some point. The growing despite trying to stop was bad, but what killed it for me was him choosing to ignore previous choices to make whatsherface (the cute one you end up staying with towards the end) straight instead of les/bi.
Personally, if they hadn't given me the option to stop, well, it's not that I like big boobs too much, but at least I know they're going to keep growing until Dev wants to. What has taken me out of the game is that, after deciding that I wanted them to stop growing (and several times) in the end that choice was completely ignored, and this bothers me a lot.
Either the fix is that they let me go back to the point where I wanted to stop (or better choose the size that each one wants) or personally that they stop now doesn't help me to want to continue (sure at some point it has to stop growing,
but if they allow me to choose and then ignore me it disgusts me)
I don't know if you're talking about Leah or Ashley or both... In any case, if I have the option to avoid any lesbian scene I take it, so in my game I decided that they were straight (I think in the end you did it to both, I don't remember good).
Although you're right that apparently this choice didn't have much of an impact either. In my opinion they remained bisexual. In any case, even if lesbian scenes don't interest me at all, if I can skip them using an appropriate button I don't give them the slightest importance either. But ignoring the player's choices doesn't seem appropriate to me (personally, it's not the thing that has bothered me the most, but it's still not nice)
