As an asexual, I find it to be annoying and distracting.
That is a more than valid complaint. From your perspective.
I want to play a game with an interesting story, immersive environment, good gameplay, and challenging (but not frustratingly hard) objectives.
That is also a very valid set of preferences, and props to you for knowing exactly what you want as a consumer.
If a game is clearly advertised as a porn game, that's one thing. But if you have what looks to be an interesting and fun game it can be ruined by putting that stuff into it.
(As above) - yes, I imagine it could ruin a game for you.
But for me, and a lot of other people, it would not. It might even
enhance the game, if done carefully. Also:
Like I said, if you want to see that, that's what porn is for. Keep it separate from other media.
Porn serves one purpose. The presence of a sexually titillating character in a fictional context, whether game, book, film or other medium serves a range of other functions.
Ultimately:
I want to play a game [...]
Make it, pay people to make it, or reward people who make it by buying it.
I'd love to play a game like that too, but I (and many other people) do not object at all to the presence of sexual content in our fiction. Not even our interactive fiction.
