Tips 🤪 please

Hello! I have been having some nice time with this boy; but the last two times we had sex, the first his penis died literally and the second he just can’t finished :( so I have been thinking if it’s because of me or because he have been too stressed and tired... someone have been through this before? Can you give me some tips/ advice/ recommendations to drive him crazy 🙏🏻 I want him to past a great time with me and enjoy the moment, and of course give him something nice to take out all this stress (sorry for my not too good English, I’m “latina”) Jajaja thanks
