Love husband but TERRIBLE SEX

let me just start off by saying i love my husband but the sex is TERRIBLE. i’ve tried countlessly to show him what i like, teach him, coach him. And it’s STILL bad. The sex is so bland and i can’t help think about my ex during sex who knew how to take care of my body. My husband does ZERO foreplay and zero after care. He just gets turned on puts it in and goes until he’s finished and more times than not im left completely unsatisfied or faking an orgasm because i know it hurts him that he can’t turn me on or make me finish… our sex never last more than 2 minutes and afterwards i’m left to finish myself… while he gets on his phone, cares for the baby, or tries to kiss on me while I FINISH MYSELF.. The past couple of times i’ve been so turned off i haven’t even been able to finish myself because i’m stuck in my head thinking about how i can tell him in a nice way that the sex is terrible.. i don’t know how much longer i can do this.. it’s so bad it’s starting to leave me feeling unsatisfied in our relationship too…
