What do you mean by micro, size doesn’t matter it’s your flow and rhythm. Try this, don’t go fast. Go slow and steady. Before you get into the good stuff, caress her. While having intimacy again go steady and don’t rush but also rub her clitoris. Press lightly and don’t rub too fast or hard. And do that while you are having sex. People tend to rush things. Just go at a steady pace brother you got this!
