My boyfriend cant finish with me

Me and my boyfriend have been having sex for about 4 months now (19F and 19M). We have since had many conversations regarding his ability to finish. He has made it very clear to me that his sex drive before me had been really low to non existent, resulting in him not jerking off almost ever. He has told me there was a point about two years ago he watched porn alot but never again since that. Recently, he told me he got too horny after we had sex alot and he never finished that he finished on his own for the first time in a long time (still taking him almost an hour). I know he loves having sex and his sex drive is much much much higher now as it took him almost a month to even be able to stay hard, i just cant help but feel like im doing something wrong. His previous girlfriend he had sex with apparently once or twice and he finished, although he told me he forced himself to do so. I feel defeated and i know hes just happy to make me feel good but its starting to make me feel insecure. He claims it is due to his mind not being able to focus as he is looking at me, using his body, etc. (He isnt taking any anti depressents or other medication at the moment). What should i do?
