The Ponderings of Young Toga

I would like to add on to this argument. We know that Twice clones are their own individuals. They have sentience and are not controlled by the original source, as evidenced of course by Twice's clones turning against him. Furthermore, the clones share the memories of the original so they are not aware they are clones outside of being informed as so. Therefore, they are still multiple sentient creatures that posses the ability to consent or deny to sexual activity on their own, rather than being a single entity doing so in multiple bodies, i.e. Cerberus from Helltaker.  In conclusion, if Toga made a clone of herself the clone would need to also decide to have sex and would have to be attracted to "herself". Ultimately the decision making and attraction needed to arrive at that point arrives at gay. Toga and Toga would both be attracted to a woman who happens to be identical in every way except having transformed into Izuku. Though of course, since they are both attracted to Izuku, and would need to simultaneously be attracted to each other with one disguised and have the attraction to Izuku, we can just call it pan. Toga is this canonically. She doesn't care for someone's gender, she is just attracted to them.
