I need advice! My boyfriend finishes fast

Hey guys I need some advice. I’m in a new relationship with an amazing guy and we’ve been starting to have sex. The first time we did, he finished very quickly, and then we had a heart to heart and he told me his last girlfriend cheated and broke up with him for that reason but it doesn’t bother me because I can literally see myself being with him forever but I’m just curious if there are ways to make it last longer or “satisfy” myself more during sex?
