needy husband

Is anyone’s else’s husband about the same? we are both 21 years old. It’s taking such a toll on me. I work full time, clean/take care of the animals and house myself. as well as the kids(3 and 10 months) with no help from him, except for him MAKING the mess. He expects sex all the time, and if I don’t, he will be in the absolute worst of moods. he is constantly touching on me, even around the kids, which i cannot stand and have asked him several times to stop. It’s gotten to the point that whenever he touches he, i literally cringe. It’s gotten to the situations of if i ask him to watch a movie, show, or if i want to go out with some of my girl friends, he’ll expect sex as a “return”. I’ve tried talking to him about this, or him atleast doing a house chore like mowing the yard so i don’t have to like i do now. he’s either at work, sleeping, begging for sex and groping me or on his video game. I’m at a loss. I can’t stand to come home anymore because I know as soon as I lay down in bed what is expected of me.
