too dependant on vibrator, help?

my boyfriend and i are 20 and just recently lost our virginity two months ago after dating for 2 years. it was rocky at first, it was wayy too painful and i bled alot more than i was supposed to, so i went to the doc and he said he couldnt find anything, but to wait a month before trying again, so we did that and everything smoothed out from there. no more pain, no more blood, and we're really enjoying it, except for one thing, i cant orgasm without the vibrator. he didnt mind at first, was just happy i could orgasm, but now, he's starting to get concerned as to why he alone cant get me over the edge. everything he does feels good, but just not enough to get me over the edge, so what can we do? we're quite experimental and have tried a few positions, doggystyle is our favorite, and we've tried many techniques and none have worked. any suggested positions to hit my g-spot? also, he has brought up the idea of anal, im not against it, but im not exactly for it either. any tips? anything that if we tried anal, would prevent the entire thing from becoming a disaster? maybe it would just be taboo enough to get me over the edge..who knows?
