sex help ?

I've been with my boyfriend 4 years .... I've never watched porn & he's been my second partner . I'm not really well experienced on riding & I just really want to suprise him, usually he always does the work on his own during sex... can anyone please help me out with some moves .. when I ride what is better ? Moving forward and back or up and down ... I really wanna take control & please him... can any of you ladies give me any kind of advice, maybe even what you do to please your man ... please & thank you
