BELLUM. also the way Jack's sex scenes are so tender
for such an intense person, you get the sense she's making love to her partner (well, being made love to ; both in the canon scenes and in the female Shepard scenes that were cut and added back in by mods, Jack takes a submissive / bottom role) rather than simply having sex or roughly fucking
it's not meaningless or just for physical satisfaction, it's INCREDIBLY emotional
and that is. very new for Jack, I think
she's so much more used to lust and meaningless sex that doesn't have emotions mixed up in it
to the point that if you have sex with her before any emotions are involved, she basically doesn't want to talk to you again because, well, you had your fun, didn't you ?
but sex with feelings involved ... shit. it opens her up and takes her apart
even when she's the one in the top / dominant role, it's getting to take care of someone else, it's someone trusting her, it's still someone treating her gently even though that someone is underneath her and she's the one in control
considering her past as a survivor AND her past of basically only indulging in meaningless sex ... like. the first time she has sex with someone, who likes her, who cares about her, with emotions stitched into it, that is THE first time she's had sex where she actually feels ... like. TRULY fulfilling ??
I could talk about this part of her forever honestly. she THINKS she doesn't need the feelings side of it to be fulfilled during sex, but the truth is, she does. she needs to feel like someone cares about her beyond just her body, even though they very much like her body. she needs them to touch her and want to be touched, and still be there in the morning and want to kiss her and want to have sex with her again but also want to hold her hand and let her cuddle them and comfort her and let her comfort them
she loves sex. don't get it twisted. but to be actually fulfilled and feel genuinely safe in a relationship and not feel like she's being used, the ROMANCE needs to be there. she has to trust them to touch her without hurting her (unless she says she wants to have some pain), she has to know they trust her for the same, she has to know that if she says "actually... can we not right now?", they won't be upset, that they're happy just to BE with her, and she has to trust that they know she won't be upset if THEY aren't in the mood
I really could yap about this forever. Jack has tried so hard to separate sex and romance in her mind, but for any kind of relationship to be there and for her to have genuinely fulfilling sex and lovemaking, she has to come to the realization (and she will, after the first time with someone who cares about her) that she, personally, can't or shouldn't separate them.
