The only reason Rachel was upset with the MC playing with Nadine was because she didn't like Nadine, not because he was having sex with someone else. Of the serious relationships the MC has cultivated so far:
- Sarah accepts that they are blood related and is not possessive.
- Rachel has already defined that her main concern is a stable romantic relationship independent of sexual playmates. She also has at least one other lover: Tyna.
- Rosalva has accepted a submissive relationship and seems content with being the sex-slave of the MC and whoever is his partner.
- Tyna's relationship with the MC has not yet really developed but she is very aggressive and dominant. However, she is already Rachel's lover and has had no problem with her relationship with the MC so, as long as she can continue with Rachel, she probably has no problem with the MC having playmates.
- Shasha is the only one with real jealousy potential. She is extremely loyal to and protective of Sarah and this may indicate her being possessive if the MC chooses a relationship with her.
However, none of this will matter once Liz makes her move, destroy's Warren's criminal empire, burns Jack at the stake, and reclaims her precious baby boy from all of these sex-crazed harlots. GO GET 'EM LIZ!!! <cough>
Sarah seemed extremely possessive of the main male if you ask me. Especially seeing when she tried to make the clean break from her brother only to cock block Shasha the moment she was getting it on with her brother.
Rosalva does have another path that the BON hasn't brought about yet so for all we know that path could lead down a different road.
as for Shasha are you sure about that? Loyal to Sarah? at first maybe but she did have her own ulterior motive. She was trying to claim Sarah's brother from the get go which was why she continued to push Sarah into dating someone else. While I can see some good in her actions due to in the clash it would indirectly prevent an incest relationship (not that it would seeing as the main male is now balls deep in his aunt and cousin as well) she did try to take him for herself.
Also if you don't choose her she tries to take pictures of the two of you going to a hotel to get it on while Sarah herself literally mentioned that her relationship with Shasha was falling apart and wouldn't be work anymore.
So to be honest maybe it was like that in the beginning but in the end? I don't see it the moment he chooses one of them.
Though as for the possessiveness I can possibly see it happening especially when Sarah shows her jealous side the moment Shasha quest starts up.
Though with Liz that would be a sight to see. her wreaking the organization, killing Jack, and finally taking the Main male from the others so she can have him all to herself. Though to be honest she might need a nuke to do that. The main male is already balls deep in the following
Rachel
Nadine
Pam
Rosalva
Calorine
Brenda
Lizzy
Clarie
Dory
Jet
Marge
Morgan mother
Ms. Taylor
Maria
Sarah (if you choose her path)
Sharon
Aunt Maggie
Mindy

Adding future updates, and the ones he can fuck one time and others and you got yourself the entire town.
