a little background: dating girl on and off for 3 years, she has never enjoyed sex physically b/c it hurts her, even after 3 years, its still tight, but we dont have sex that often....... but every time we get sexual, i go down on her and i LOVE it, and i always want to get better. But everytime i do, she kindof half orgasms, her whole body tenses up, her legs quiver, charley horse, etc... but she does not cum and afterwards feels so relaxed, and like she was expecting it to be greater. Lately, ive talked dirty to her and she liked it, i also teased her with my fingers until she couldnt stand it, then i went down on her, and same thing again. is there ANY way i can get her to orgasm and cum? i want to get her off so bad! what do i need to improve?
