Posted the same question in Mid-game section which ill now delete, think this is a better place,

Well the sum of the situation is that a coworker responds positively to basically all flirts, always plays along, good response to small kino, or atleast never negatively . Shows iois and initiates small flirts time to time. There is a ton of tension between us even though nothing overtly sexual is going on, however she seems too nervous to go out with me,

I only work with her once a week btw, and 3-4 shifts ago I had jokingly asked why none of us coworkers ever go and get drinks together after work. after some playful exchanges when she gave an "im always busy" routine, she had a sort of outburst and basically said,
"id hang out with you, but I cant, im not mixing work and sex, "

Paraphrased, but that was nearly as randomly direct as she said it herself. Caught me off guard as I was asking such a platonic non threatening question. ibacked off and made it seemed like iwasnt that interested . she covered herself a bit too . I think I fucked up and should have been more commanding, however this did confirm that's there is strong sexual tension and that its just not me.
I assume this to be ASD vs disinterest, as she has never responded negatively body language wise to my advances. She shows interest herself. And actually I continued flirting after this as if nothing happened, shes responded BETTER since she "rejected" me.

we have moderate rapport, but I usually have more with woman I bag. Sometimes its great and sometimes the tension goes to near awkwardness (never actually). Think I came off too strong and got ASD. working so infrequently is a hamper to all this, and I decided to not text with this one, so communication is small. Is the best route in this situation to gain enough rapport till shes willing to let go of her ASD and hang with me, or something else?

Also I should add how it feels as if she recognizes some of my game, and thinks to herself "that cool, your cool, but im not letting this go anywhere," I know shes holding herself back. Help me relax herself

She doesn't want to shit where she eats. Of course if you persist smoothly you could very well get somewhere if you take all the responsibility and she feels that it 'just happened'.

(Could've said to her right after her 'sex' comment, said teasingly): "Are you always this forward or is there something wrong with your hearing? Who ever said anything about sex. Get ur mind out of the gutter, I said drinks, as a group, not sex" etc. Basically to break her frame and "shame" her into going out. Then change the terms at the last minute so it's just you and her for drinks.

Bottom line gotta get her out of the work environment and to a place w/ her where you can escalate the kino.
