On missing the boat sexwise

Today I feel like crap. When did sex change from being a shared fun activity that draws people closer to being a game of taking turns that drives them apart? My turn. His turn. if it's my turn first I know he wants me to hurry up and get there so he gets his go. Quick quick. Then he doesn't get there because he goes limp while I give him a hand job. I feel embarrassed. I guess he does too, though he hides it well and blames it on nature, old age etc. He always puts me first. But I want real sex. Not teenagers heavy petting games. Not frustrating second best. I want the real deal. I want to wrap my arms round him and feel him inside me. I want us to be enjoying it at the same time, not to feel like I'm the floorshow and he's the audience. He's 67 and might as well be 97. 
He says he's like a leaky tyre. I tell him he wore it out when he was young. We wonder if men only get so many erection minutes in their lives and that he used up his before we met.  Because he always took a long time to finish. Sometimes a couple of hours. But that was years before me. With other women. So many of them. He says he was like those batteries - ever ready. He said he was always hard. He thinks the valves that hold the blood in are worn out. He says I met him 10 years too late. Why does he think that hearing that will make me feel better? 
i'm 58. Too young to live the rest of my life without sex. He enjoys oral and handiwork more than intercourse now. He needs the extra pressure because old men get less sensitive as they get older.  But even that can't keep him hard now. It's getting worse. What's gonna happen to us? When he was young he had a FWB with a woman 35 years older than him. For 5 years. Once a week. She cooked for him and they had sex in the afternoon and evening. All afternoon and evening. So now I get nothing. There's nothing left. I hate her. That's what I want, I want to be that old woman, with a hard young man, not this one with the old soft version. He says boys these days are not like he was, like I wouldn't be able to find one. They wouldn't want me.
My friend has a newish man. He's old too. Same age as mine. Says she has no complaints and that he keeps her very happy. The inner 8 year old me screams It's Not Fair! It's Not Fair! We're going out together tonight. I'm drinking. First time for couple of months. I will forget for a few hours
