Orgasm...

My boyfriend and I are a fairly new couple and have only been having sex for a couple of months. I have never had an orgasm with him.. for those of you that can, how do you get off with only P and D action? What position seems to work best for you? And for those of you that clitoral stimulation is how you get off, what are some tips? He and I are both young so vibrators and whatnot aren’t accessible to us. He rarely touches my clit during sex so how can I suggest he do so without making it awkward?
