HI,
I agree that ladies are bit curious as well as sentimental, be very inquisitive in collecting personal and professional information but they are not dangerous. Like you, I also worked for very long time with guys and very few ladies and now working with only lady staff. I being a lady, did not know how to handle ladies ??? Trust me, may be few might irritate with silly questions, but ladies are always co-operative, will come forward to help you in times of difficulties, they can very well understand your problems and try to save you from guys who tries to take advantage.
If you are comfortable you can share your feelings with one or two .. so that you will feel light to know you have someone to share.
Otherwise like suggested by many, politely you can show them that you are not comfortable with personal questions.
Gents also tries to collect personal details through others. Some will take advantage of the situation. I had my manager who tried to collect information about my relation with my husband through my other lady collegue !!!!!!!! though I had no family problems. In one of my office, married guys misbehaved with lady staff who were not married untill they were 29..30 years. Also some use to take advantage of lady collegues whose husband is away / abroad etc., I am not blaming the male gender, but trying to say that Good & bad are qualities of human not biased on gender.
So my dear friend, be relaxed..........enjoy working with new set up....
