Husband is selfish in bed…

My husband is very selfish in bed and I’ve tried to talk to him about it but nothing has changed. I’ve been all over him telling him I want him to get me off bc I haven’t in a while and I always will give him random head or he will ALWAYS get off but I do not. Just now after a week or so we had sex and he finished and I’m just stuck feeling frustrated again….. like I know it’s a stupid reason to be but have you ever been on the edge of getting off for like a month straight? I wish he would want to take care of me like I do him…
