Women exist to please others. Even if that means their body being used for sex. When I have sex, I put my entire being into it throughout the session or night. I let her know that I want to pound her with everything I got. And due to my d*ck size, I constantly can hit the end, which causes all kinds of pleasure for me and her. She will say it hurts, and it likely does, but it's a good kind of hurt. One that she remembers and why they keep asking me for seconds and thirds.
What some of you have to accept is that when you are using her for yourself, you are already making her happy. Sex is one of the strongest forms of attention to a woman, and the energy it provides unlike any forms of physical stimulation other than violence. Even if you finish quickly, she still got your time and body and semen. Have some self esteem.
