[NSFW] Are most of us really straight?

Lock heterosexual people up in prison and the vast majority will opt for homosexual relations rather than celibacy. Not all gay women play with dildos and strapons, but enough do to suggest they could enjoy heterosexual sex in a pinch. The same goes for heterosexual men playing with dildos and strapons, or letting their female partners penetrate them with such toys. Why all the partitioning—the big deal about I’m exclusively straight, or I’m exclusively gay? It sure seems we are all or nearly all inherently bisexual.
