>>2410476that's the problem, this things depends on every couple's experience, tastes and personalities. What I can tell you, that works as a general rule, is that (1) you must be cool and aloof - or tend to be it - most of the time, with a "I have business of my own" mindset; (2) listen to her and ask her questions, it's really important to make her talk and follow her train of thoughts, making remarks that can be useful to her and also fun, and (3) make her laugh as much as you can.
Keep in mind that "being sexual towards them" is not what a girl would expect at first, you have to first make a pinch on her physical comfort zone so you can trespass confomtably, and for that you gotta start touching her softly while making jokes, after she touches you first, for instance make a joke really cocky and innapropiate-ish that makes her say "I can't believe you said that!" so then she goes and softly hits you on the chest, then you can make something similar (without being girly ofc, and if you say something innapropiate think REALLY WELL on what you'll say)
