Been married a year altogether for what feels like forever

We use to have amazing sex that would last what felt like hours some nights really was hours

And I was left beyond satisfied

But ever since he went away for a month for work in April/ may

Lucky if he doesn’t finish is a 3 mins time frame

And it’s so dam frustrating

Anyone had to deal with something like this anyone go any advise

Iv tried talking to him but all I ever get is I dunno

His go to on any question he doesn’t want to answer

I’d understand if I was being a dicktease

But I’m not

Even when I use to he would last so much longer
