ZW62: I have been very blessed with a great girlfriend who I love dearly. She is about 5 feet tall and about 100 pounds. Now I have been with short girls who can take my length with no problem, but she can't. Everytime we have sex, I have to go real slow. I have never been able to fully penetrate, or speed up. If I get too into it and accidently pushed to far, I have buckled her over in pain causing me to have to consol her and finish off myself. What can I do.. or what can she do to help with the pain? Is is medical? Do I need some sexual aides? Any advice please. I'm desperate.
