The problem I am seeing here is your are trying very hard to box all women into one category, which is the only common category is that they are all women. Every woman is different, in general every person is different. What may turn one woman may turn one woman completely off. There isn't just one answer for women in general same way there isn't one answer for men in general.

For me yes I have to trust a man before I can be involved with them emotinally or sexually, I had to trust my boyfriend before I could be sexually involved with him. It is a lot different for women in that we have to think about the potiental of pregnancy. That is a really scary thing, especially if you don't have a partner to trust and be with you if it was to happen.

Women do get turned on and have sexual arousal just like men do, it just isn't as noticable because biologically it is different.

The biggest thing, as I have stated in a previous post to one of your topics, is to get to know a girl as a person and individual, and from there you will learn more about whatever person you are interested in. No two people are alike, and everyone has different interest, starting from common interest is a good way to start even on a sexual ground
