Your blog came up in a Google search about the twitch. All of the other ones say it is a mating behavior, but your two young females twitch at each other?
This is a greeting. We will wave to say hello to a child we don't know, and we'll wave to say hello to our adult bootycall. A wave is not in itself sexually explicit- it's a greeting. The hognose twitch is not sexually explicit- it's a greeting. Sometimes they go into a sort of trance and just twitch so hard they'll force the air out of their lungs in little hisses while repeatedly bumping into the other with their nose. Still not sexual in nature.
A child will hug its mother to express affection. Sexual partners will also hug one another to express affection. A human child hugging it's mother is not trying to have sex with their mother, just like a young hognose twitching at an adult/baby or slithering over another hognose is not trying to have intercourse with them.
Hognoses are not the only ones to use this physical display as a greeting. See this adult rattlesnake inform multiple other snakes passing by (most are babies) they are friendly:
Some respond in kind, another snuggles with them. Snake culture involves a lot of cuddling, and I think that's wonderful! ❤
Adult hognoses will greet other adults and may try to initiate coitus afterward, which includes much more than just a twitch. It usually involves the male stimulating the female in her erogenous zones and she may choose to accept or reject him. Twitching is not this stimulation or attempt at intercourse.
It is social behavior that only occasionally leads to romance between adults, and friendship/playtime/cuddletime for babies.
