I’m not exactly sure what you mean by the “being-to-being passions” — so long as you’re with her and not in a PCE, there will be a feeling-being interacting with a feeling-being, which will necessarily come with moods, feelings, emotions, and their concomitant vibes and psychic currents. There is no way to prevent or stop any of that, outside of having a PCE
The degree to which ‘she’ affects ‘you’ will vary — eg if I’m in a normal state, then my partner’s negative moods or emotions will often trigger a “resistance” in me, a dislike of that she is feeling, and a wanting her to stop feeling that way. This latter can be mistaken for caring but actually it’s a self-centered empathy response (me wanting to stop feeling bad in response to her feeling bad). While if I’m having an intimacy experience, I automatically ‘perceive’ the totality of the situation — she is a fellow human being, she is having a hard time — how unfortunate! What can I do to ameliorate this? It’s a much more genuine caring, and though I still fully recognize and to some degree am directly affected by her feelings, it’s nowhere near the same, the enjoyment and appreciation of being alive practically does not diminish. Incidentally this way of handling things is much to her benefit too!
As to attraction or sexual desire — I’ll just say there’s lust, and there’s actually having sex, and they actually don’t necessarily have anything to do with one another 
. Which is sort of funny. I’ll just say that rather than trying to control these things either ahead of time or in the moment, just go with it and see how it goes. It’s not an actualist ‘sin’ to feel lust or desire or want to have sex with someone — just enjoy it! Whatever upsides or downsides you may imagine — the best way to discover is by experience, with more experience it will become clearer. I fully endorse your pursuit of these matters!
