Going soft during sex

I tried sex with multiple women, all three of them has loose pussy as they are prostitutes , so Iam not getting that firmness while having sex so dick becoming soft . I really donno what might be the reason for dick becoming soft during sex but when I masterbate it is becoming hard for long time

Might be a grip issue. Donโ€™t hold it so tight when you masturbate, or try going a few days without it. Also it might be the condom thatโ€™s why it doesnโ€™t feel as good but itโ€™s a must as everyone should practice safe sex
