Ig I just don’t get it

My man can never finish from sex and idk why bc he’s literally always down to f!ck like always but he always finishes himself off . And I asked him why and he’s like bc I don’t finish inside and I was like yeah I understand that but like you can pull out?? And he’s like well I just have a lot on my mind but that doesn’t mean I don’t want you. Like what’s your opinions. I mean it’s been like that since we been together ( a yr) but I just don’t understand none of my past partners have had an issue finishing from sex and it really bothers me that he does.
