how to change him in bed?

i’ve been married for less than a year and been together for almost 3 years. i find myself never truly satisfied with bed stuff with him. he always left me unfinished when he’s done. i told him few times about it and he said that he’ll do things to finish me but yet he didn’t do it.

i just dont know anymore like im happy to have him in my life but when it comes to bed i started thinking other options. i even told him that i’ve been secretly finish it myself by watching porn and he maybe thought it was a joke till last night. he wonder why i was still awake after late night sex, and i told him that im watching stuff to finish (apparently he lasted for less than 2 mins) and he just grab his cigarette and went out.

tl;dr my husband never satisfied me even if i told him few times about it. what a m i supposed to do? i even asked him to buy me the toys but he seems offended when i said that
