Because there isn't canonical sexual intercourse in
Transformers, there are at least two different philosophical factions among
Transformers fans based on how they believe the Transformers have sex:
- Spark sex, where they do more abstract robot-like things like jacking in and sharing data (sexually)
- Sticky sex, where they just do regular human-style penis/orifice things, except they're still robots
Pardon if I got details wrong; I learned this while following a personal semi-cow. Transformers are kind of alive inorganic life forms due to some divine spark thing, like golems with free will more than biomechs or EVA units, but I'm not autistic enough to understand the lore better than that.
