there are many reasons why finding bi content to be hard. like it or not, most people take their orientations as a hard line, be it straight or gay and for some reason, many of them take the possibility of content for the other side as offensive.
things get muddied when you throw in a trap(pun intended), i still belive that, given the choice to interact as you want, a trap only adds more uniquiness to the cast.
its kind of the problem with ntr, there are so many variations and yet, people take ANY content as a hardline.
if you are okay with the single trap once in a blue moon, you might be okay with the newer games, like summertime saga, Dr amana, personal trainer or MVN.
as a side note, i know of a couple of games that may interest you:
warlock and boobs, basically the MC can "interact" with diferent people of both sexes.

my new life, dont let the tag stop you, this game has butloads of content! with the MC being able to "interact" with diferent people, be it males, females and "inbetweens".

as a side note, you should give those text adventures a try, they can be even better than "normal" games, since they need to describe the scene, seriously, its kinda sad when a game like camp pinewood, with such an amazing art, can has some of the worst and least rewarding scenes, when you compare with something like Caelia kingdom.
hope that helps.
