Married to.....who?

I got married May 2nd to my husband of 8 months literally everything he did was perfect we have a brand new house nice cars decent jobs everyone we know thinks we are head over heels happy but at home the only time I get attention is when he wants sex & he wants sex ALL the time but the attention isn't loving & passionate it's begging me for head begging me to sit on his face or let him cum on me while he jerks off to porn. I have 2 kids from a previous relationship & he's always getting theirs &  my hopes up that we will go do stuff like fishing, the park, for a walk then when he decides to lay in bed watching tv or being on his iPad they & me suffer. I end up taking them myself but I get so angry that I am married but always doing everything alone like I'm a single mom. I have tried over& over& over begging him to go yelling at him bc he won't and even crying it's like I'm throwing a temper tantrum and he still won't budge but the second he wants to finally go we all have to be ready to go do what he wants. I don't know how to feel or what to do I'm lonely & feel like the only reason he married me is bc he wanted a wife and guaranteed sex. :/
