from my point of view, if you have a girl that is 'contained' or as i call it a 'closed book' you have to view her one page at a time, most girls who are like this, are like this becuase the males they have known throughout thier life treat them bad, so you have to be the guy who is different, for example:
instead of watching a movie, which tbh is quite a common thing to do, and its not really making you stand out, go for a walk at night and watch the stars, will be cold so a good excuse to get close and slip in some cheeky kino

, also shows her a deeper emotional side, without directly saying it. also gives you quite time to talk and connect.
this is exactualy what i did with my last girlfriend, and it worked a treat.
try and show your different without bragging about it, for example:
i took my girl to a club once and my male friend was thier, being who i am i grabbed her and told my friend 'Quickly tickle her' he said 'i dunno where i am allowed to touch and where not to' i said ' anywhere, i dont play the jelous boyfriend' this got me a few DHV points, KERCHING!
as for her not showing kino back, maby your looking for somthing that isent their?, shes allowing you into her life and personal space, just sit back and it will come eventualy, some girls and more closed than others, patience is a virtue.
another quick thought about only hooking up 3-4 times, whats so wrong with that

? not hooking up every possible second your free only shows your NOT NEEDY which ofc is a good thing, dont get addictied to a girl it will push her away slowly.
hope this helps, and gl
