Everytime I try to stimulate my girlfriend and help her achieve orgasm she gets so frustrated and can't. She has never had one before. She gets to a point, where he feeling is so intense, that she makes me stop. She said she cannot take it. I know when she is giving me head, it gets to a point where it is so sensative that I almost don't like it. I am just wondering if I am even close to giving her the big O and any tips would be gretaly appreciated. Thanks a lot.
