The argument that "Alison can be screwed up if you don't show interest in her and go for someone else" not only doesn't contradict my point (that all Ian need is to show actual interest) but isn't even true -- keep Alison at bay long enough and not only she will invite Ian and pretty much throw herself at him, but even forego any silly thoughts of condoms etc.
For the others, passing checks and "not ending date with wrong answer" is also something Lena is required to do at certain points. Not only that, but in some cases (Jeremy) she potentially has to spend will point to push things through. Or, let's put it this way -- at no point in the game i've felt Ian had it any harder to drown in pussies than Lena had to work for multiple dicks. And that was on a blind playthrough, with no cheats, walkthroughs or anything like that. The attribute checks are easy to meet, unless one is intentionally avoiding their development. So, no, i don't think this supposed difference of "Lena has it easy, Ian has to work for it" is really true.
