She makes him cum multiple times

He watches porn and masturbates in private, while I watch and masturbate with him right next to me in bed. He has only ejaculated a few times during sex because usually it takes so long that we both just get tired. I had another guy that had it—but not this severely. Why does he last so long? Bad feelings should not always be interpreted as deterrents. How many times can a woman cum after sex?

I bought some lingerie, I even squeeze my muscles down there. How many times can you cum? How many times should I cum in one day? How many times can a man cum? How many times can a man cum in one sex round? After ejaculation, there is a refractory period during which the penis goes flaccid, sometimes completely flaccid, and sometimes only semi-flaccid, depending on various circumstances such as level of arousal, level of stimulation, age, and etc. Sex has become too cum-focused.
