Generally, I play whatever I want to play based on looks, gameplay or characters/story, and I may come across games that would be considered risque, certainly. If I buy a game that involves fanservice, I don't buy for the fanservice - I buy for the game. And while fanservice can be a plus for sure, I won't buy if the games other aspects aren't interesting enough to justify the money.
From the games that I acquired based on those bulletpoints, Senran Kagura is probably the game that's most "in your face" about the fanservice and likely the game series that I would least play in front of my parents (which is why I'll be getting the Vita version of Estival Versus).
I did tell a few very good friends about these games (even though they generally only play PC games) and they are the type of people who would be to embarrassed to buy something like Neptunia in a store, but they are okay with it and we joke around about this stuff quite a lot. They always want me to buy these games in store to get a laugh. It's lighthearted fun.
I also have a list of every game that I own that is more or less viewable for everyone on the internet, and people that know me well will be able to associate this list with me no problem. Generally, I tend to think that if they'd recognize these certain games on the list, they'd know about them anyway, so it wouldn't hurt me in any way. That's why I remain very open about the games I play, even if some of them are certainly risque.
In that sense: Akiba's Trip is extremely harmless if you ask me. One of the games that I'd have absolutely no problem with showing around, especially since it's all very tongue-in-cheek and thus easily explainable if you ever feel the need to. It's also a game that I have no reservations about playing on public transport - I have played SK on the bus/train before, but only if I feel 'unobserved'. There's certainly some shame involved there, I won't deny that.
