I say no.
Your significators, Moon and Jup for you and Merc for her, are disjunct. That means they do not aspect at all, are five signs apart. So you do get each other, do not see eye to eye, so to speak.
When Merc moves into Gemini and you as Jup remain in Sag, there will be even less of what little interest there is between you now.
Hi I met some young girl today. And I have a hunch that she was sexually attracted to me. i am jupiter in first, she is mercury or mars..
we were in gym. she is 22 and i am 27. what would you say?
I would say your hunch is correct, Mercury being combust by your male planet Sun, Sun is your sexual side and basically would mean your charms working on her. She is overwhelmed by the masculine attraction.
