It is normal for boys to react quickly for the first time. Because the first time, I will be very excited and the stimulation will be very strong, so I will shoot it soon, and the time is very short. My girlfriend is right to say that you are quick, because it is not the first time for her. If so, she won't say you are quick, and most girls will bleed for the first time, which will be very painful. They don't want you to fuck her for a long time, and they won't say you are fast.
