@Alex "modifying yourself to be more bisexual" (and thus open to a larger pool of partners).
in general, I find that thinking through the positive aspects of your less-favored gender can reveal latent attraction to aspects of them. Maybe you find penises repulsive presently, but actually like facial hair (or vice versa). Maybe rough hands aren't appealing in the same way as dainty ones, but maybe they hold their own appeal and strong suits. I'm not sure how viable this is for someone who's kinsey 0 or 6, but I think it can move 1s and 5s a long way towards the middle and I think relatively few people are kinsey 0 or 6. I think a lot of people report themselves as entirely heterosexual or entirely homosexual because it's socially simpler that way, it's normative, and they may not have thought about it that deeply.
