lol The point of dating is finding someone you're compatible with. Obviously ya'll are not. Leave now. He wants to play video games all day, which doesn't nod towards any sexuality really, and you want him to get it on with you. Go find someone who wants what you want and be happy.
It is common in relationships for either side to not feel sexually intimate with their partner. A lot of womyn are saying "well, maybe he is bored of you.". But have you ever taught maybe he doesn't feel close to you? As human beings we evolve all around as time goes on, and it is necessary for couples to always continue to get to know each other. So start slow, go on a date or have a date at home where you cook dinner watch a movie, and see how that feels. Or have dinner and talk. Talk about anything but make it a positive conversation. If in anyway he goes sour? That's when the concerns should come into play.
Most of everyone in here is right, but you need to talk to him on how you feel and lesson to what is going on with him. In a relationship it is never 50/50. What is need is communication. So the both of you know where you stand. Before you just dump him.
