Then, there is sex-indifference. These people are still asexual, and can even enjoy sex, but they have no desire to start it themselves. They can do it to please a partner, but beyond that or taking care of a libido they’re usually just…meh. You can joke about sex around these people, and may get a few chuckles, but you won’t get offended or disgusted stares (at least not because of their level of repulsion).
And finally, the sex-favorable on a personal level. Completely okay to joke around, these individuals might even be able to relate to what you’re saying. They enjoy sex, just don’t find anyone sexually attractive. Yes, there is a difference. Weird to some, maybe, but true.
