I'll get to the point, I'm currently dating 3 girls on the same time.

It's cool, none of them seems too much interested in a relationship (all of us are kind of too busy for that, or they don't feel that vibe with me) and we're having fun. Two of them know I have other women, one doesn't but never really pushed for an official relationship either so I'm not much troubled.

Now, I don't feel like I don't have success with women (but I got to say that opening and closing strangers is still an issue, I still limit too much to social circles and friends of friends) but I'm having a hard time sexualizing and avoiding being a friend in my university circle.

Example given, there's this HB7 I kind of feel very attracted to. Problem is we always end up talking about university or stuff, seems also hard to isolate her without other people noticing and instantly talking about it.

I'd like to escalate or atleast maintain a "sexy" frame. I know how to do it on a date 1on1 or while picking up, but in this university enviroment it is much harder because the ASDs are extremely high (everybody knows everybody there).

What would be a good idea to break this "friendly" attitude of her. I don't want of course let her know I'm into her, but I want her to think about it and stuff.

People in my university know that I like women and I tend to have multiple open relationships so escalating with her will instantly make somebody talk to her about what's happening.

Probably I'm taking all of that much too serious and I should do something easy like take her for a coffee at campus, point is that she's 100 % of the time with another girlfriend and they go all the time together.
