Your opinions

Suppose Jill wasn’t fully aware of sexual contact, she is 16 and underage by the Wisconsin laws. Jack is 18 and more aware. Jack knows that Jill isn’t fully aware, but instead of telling her that any sexual contact can cause STDs, he hides it from her and tells her that they’re not having sexual contact. Jack gets sexual favors from Jill, but she’s not fully aware of the repercussions of her actions and Jack withholds this information from her. Falsely making the partner believe the sexual act is not as serious as it is. Jack continuously pressures Jill for sexual favors profiting off of her miseducation. They never have intercourse, but exchange oral sexual activities. He tells her he is saving his ejaculation until they have “sex”, continuing to minimize it.

What do you guys think? Is this just?
