Life Hacks/Dante's taboos and interests
Sexual history
Dante's mother has made it clear to him he is free to explore his own genitals at any time in the privacy of his bedroom or the bathroom, but also knows from his mother that most people freak out when children do that sort of thing. He agrees with her that there is nothing wrong with him touching himself, but has developed a very paranoid view of the world outside his house so far as what other people might think if they find out. He has been placed under the impression that everyone other than his mother is like she says his grandparents were on this subject.
Dante has come to realize there are a lot of things his mom does different from other parents, but has accepted that her methods are actually better than the rest of the world and based on what she has learned from the small number of people who know what they are talking about. He feels ashamed of sexual acts while interacting with people outside his family because he is paranoid about how they will react and that his mom might get in trouble and/or he will lose friends, but does not think there is actually a problem.
Once, while he was taking a bath with his sister and asked his mom about the slit between his sister's legs where a penis should be, he was invited to touch and explore his sister's privates and did so as she explained to him how a girl's privates were different. He figures his mom would not be averse to him repeating this exploration of her body on his own, but has not done so for fear that too much interaction with his sister and the things she likes will increase the amount of effeminate traits he has that he is so embarrassed about.
