Real sex after quitting porn

(22 yro F) my boyfriend is 2 weeks free of PMO and our sex life has imroved drastically. he seems way more engaged with me and focused on making sure i finish too. he also has been trying new things with me, whereas before it felt like a routine.

but i noticed hes been lasting a lot longer which i enjoy but he seems frustrated about. last time he couldnt even finish until i went down on him. is this normal considering hes in the process of rebooting?
