There are women out there who like to have sex just for the sex of it irl so why would it be bad to portray this in video games? Of course the woman in particular in the game needs to have some personality and maybe you need to get to know her a little bit.
I don't know how deep into this discussion we want to get, as it tends to be as treacherous as quicksand, however I'll make a comment.
When it comes down to it, I don't see it as a problem, but for many people (And not even feminists or SJW's) there's a point where it crosses the line.
If you walked up to random women in the street, and offered them $1,000 to have sex with you, chances are the vast, vast majority would turn you down, even if you were an attractive guy. I'm sure there's a few weird ones out there that would agree, but I'd put my money on it being super rare (Most would question, "What's the catch?" I assume). So when you have "Sex Options" like in TW1 where bedding a woman was as simple as giving her a fucking Kikimore Claw, or Gloves, that's the point where you've crossed the line for a number of people.
On the other hand, Geralt is famous, and some people might be intrigued by the idea of bedding a Witcher, not to mention they can't pass on STD's or get you pregnant. So it's not
completely ridiculous, and that's why I personally don't feel it crosses the line, but many people out there it would, and I do understand that.
However then there's a situation like Vesna. You save her, walk her all the way home, it's not completely implausible that she would offer you a "reward" for doing that, since she's a poor country gal and you just saved her life, twice. Sex encounters like Celina, Abigail and Vesna are plausible and that's the kind of minor encounters which shouldn't be removed, and even if they ask you're totally free just to turn them down and ignore the sex component.
Ultimately I wasn't angry at all when many of the random sex encounters got gutted in TW2. The game's story and fast pacing due to the events tended to nullify that and I was happy that at least those little minor encounters (Like Vesna) in the form of the Succubus or the Elf remained in-tact. I really hope they haven't gutted those as well in favor of JUST having the main Yen/Triss romance storylines, because to me those little encounters where they made sense were neat, interesting and some times even added flavor to the characters themselves (Like Celina or Abigail) and assuming that TW3 takes itself a little slower paced with the open world, it's a great opportunity to scatter the world with a number of those situations.
However as I said, I don't have any problems with the removal of basic, "Here's a Sapphire, now fuck me", encounters with completely random women in the world (Unless you're in a brothel), because that's the kind of stuff that's probably pushing it and is ridiculous for a lot of people. When you're trying to write a serious "Novel-like" story, that's the kind of stuff that comes off as juvenile and inappropriate unless there's a REALLY good reason for it.
