It is written: “Issachar is a large-boned donkey” (Genesis 49:14). The Sages: this is an allusion to when Jacob came in from the field riding a donkey, and Leah went out to greet him, saying: “You must come in to me;” (Genesis 30:16). Issachar was conceived from their subsequent intimacy. And it is written: “Children of Issachar, men that had understanding of the times” (I Chronicles 12:33). The descendants of Issachar were perceptive men. Question: It is derived from here that a woman who request from her husband intimacy has a positive effect on their children?

Gemara answers: The baraita is not referring to a woman who demands intimacy explicitly, but rather to one who entices her husband, so that he understands she wants intimacy. They consequently have excellent children.

"Who Entices": she seduces him with words of desire and appeasement like Leah, for she only told Jacob to come to the tent, not that she requested intimacy explicitly.

A predatory woman. That is one who sits and makes fun of the words of the Torah: “She said, you shall come to me … and he slept with her that night.” (Gen. 30:16) Rebbi Abbahu said, stated "as-if" this was a [divine] inception into the story. Only God knew her motives were only to produce tribes.

“She said, you shall come to me … and he slept with her that night.” (Gen. 30:16) R. Abbahu said, God peered into her soul and saw that she only had intentions for the sake of heaven; therefore the Bible states, "And God listened to Leah" (G. 30:17)

Dinah the daughter of Leah went out (Genesis 34,1) Why, everyone who uses proverbs applies to you the proverb “Like mother, like daughter.” (Ezekiel 16,44) Yosi from Me‘ona was giving Targum...[Reish Lakish] asks [Yosi from Me‘ona], “What is meant by the verse ‘Why, everyone who uses proverbs applies to you the proverb “Like mother, like daughter.”’ Yosi replies, "Like the daughter so too is the mother, the generation is like its Nasi, the altar is like its Cohanim. Around here we say like the garden so is the gardener." Reish Lakish said to him, “You still haven’t apologized for the first comment [insulting R' Yehudah] and you insult him again?” So what about the main point of ‘all who rule over you?’” Yosi said, “There is no cow that gores until its daughter is a kicker, no daughter prostitutes herself unless her mother has. Reish Lakish and Rabbi Yehuda, “Are you calling Leah our Matriarch a prostitute?!?” Yosi replied to them, “‘Leah went out to meet him [Yaakov]…’ and Leah went out dressed like a prostitute, therefore Dinah went out [dressed like a prostitute.]”

Yose from Maon interpreted in the synagogue of Tiberias...[Rebbi Joḥanan or Rebbi Simeon ben Laqish] asked him: What is that which is written: For their mother whored? Was our mother Sarah a whore? He answered, like daughter like mother, like mother like daughter, like generation like the prince, like the prince like the generation, like the altar like its priests. Cahana used to say, like the garden like its gardener. He told them, not only did he curse me once in my absence, but he cursed me three times in my presence! He asked him, what is that which is written: Anybody wanting to formulate a simile about you will state as follows: like mother like daughter; was our mother Leah a prostitute since it is written, Dinah went out? He told him, for it is written, Leah went out towards him. One identifies going out with going out.

Where was Dina [when they met Esuv]? He put her in a closed box; Jacob said: this evil man has a treacherous eye, so I hid her that his eyes won't fall on her and take her from me. R. Huna citing R. Aba Hacohen (from Bardala); God replied: "To him that is afflicted love is due from his friend; or else he forsakes the fear of the Almighty." (Job 6:14); You withheld kindness from your friend; you withheld kindness from your brother; had you betrothed her to him she would not have sinned; you did not seek to betroth her to one circumcised, she’ll be betrothed to one uncircumcised; you did not betroth her to someone she is permitted to marry, she will be betrothed to someone impermissible. This is what is said "And Dinah went out."

R.Yoḥanan said: What is the meaning of that which is written, with regard to Leah’s conceiving Issachar: “And he lay with her that night” (Genesis 30:16)? It teaches that the Holy, Blessed be He, contributed to that act. As it is stated: “Issachar is a large-boned [garem] donkey” (Genesis 49:14). God directed Jacob’s donkey toward Leah’s tent so that he would engage in intimacy thereby causing [garam] Leah’s conceiving Issachar.

[Citing GR:] [Question:]...[O]n the contrary, Jacobs actions should be considered righteous, for he stopped her from marrying an evil man. [Answer:] we could say that Jacob had bad intentions, for he didn't want his brother to become righteous so that the blessing of "be lord over thy brethren" (Genesis 27:29) not apply, therefore he was punished.

The slight immodesty in Leah caused her daughter to sin.

Juxtapose “going out” with “going out: For in truth, Leah did “go out” but not as derogatory statement about Leah, only that Leah “going out” caused Dina to go out, and Dina only intended to go out and see the girls of the land.

§ Rav Naḥman bar Yitzḥak said: Greater is a transgression committed for its own sake, i.e., for the sake of Heaven, than a mitzva performed not for its own sake.
