I wanna go farther with my girlfriend but dont know how to say it?! (GIRLS ONLY)?

i dont wanna say im experienced but ive gone farther then making out like the "other stuff" i guess you could say, just not because im trying to wait as long as i can, but i wanna go farther than just kissing with my new gf, we have been dating for like a month and i know she would do more stuff but dont know how to say it. should i just moove in? or ask to be respectful? or let her make that decision? hmmmm difficult hahah
