Sexual compatibility

I have been dating my bf now for about a year and we are both 29. We have sex usually one day a week on the weekends. He decided on this routine really and said it felt better to have most of the week to 'build up' before having sex. While i understandthis and really enjoy when we have sex, i find that i am very frustrated sexually. I am taking care of my needs mainly and i hope im taking care of his. But hobestly... i feel like my needs are not met most of the time and the routine setup makes me feel like sex is just another scheduled thing like a job or a class. While im okay doing things on my own, im wondering how normal this is and if I'moverthinking this. I havetalked to him and he stays firm on just keeping it to the weekends, saying he is tired otherwise. What should i do?
