(NSFW) how can I be more pro-active for my girl friend to sexually satisfy her most & make her experience with all 'feel-good' factors?

it’s been quite a long time with my girl friend. we share a very healthy relationship with each
other. we feel it’s been a fun for us to be together. and no doubt that
we share a healthy relation on bed too. although somehow I feel that she is not too
much active but enjoy very much whatever activities I carry on. she doesnot speak much
and sometime her actions are very little. but whatever I do to satisfy her she loves it a lot. though
she never expressed it, but I know it. If I stop myself in between any acts
she hold my hands and pulled me closer to her. she never stop me to do anything on her (of-course to satisfy her) but
she is not at all reciprocate with her own activities on me. I dont want to lose her,
but want to know from others that what all activities I can bring out in our relationship
that she feel good about it. Women have lots of pleasure spots ( that she use to tell me). I want
a guidance from the other expert in the same field. Plz help me.
