So recently I have been presented with a new challenge that I have never seen before. I cant seem to get my girlfriend to cum when going down on her or when fingering her G-spot, I can only make her climax during sex. I asked her if I was doing anything wrong and she simply stated that she has never really came from other men going down on her. Well I am certainly not an expert in the field but I have been able to make most of my previous girlfriends cum when going down on them or fingering their G-spot without serious challenge and I haven't changed my technique much with my current girlfriend. So I am wondering is it true that some girls mainly only cum during intercourse or is she just "different" and requires some technique beyond my current understanding? I have researched the Internet and found that some girls prefer a G-spot massage and other prefer a clitoral massage but the overwhelming majority of the information I have seen states that stimulating the clit is really the sure ticket to getting her off. Any suggestions? I figured next I will try some toys, I am confident that has to work. If it matters, she is about 29.
