I didnt want to ask something so personal online, but it seems i am the only person i know with this issue. So internet community.... help me out.

My boyfriend and i have been together for 3.5 years. We live together and hoping to get married in the upcoming year. But there is one problem....

He never wants to have sex with me anymore.

Its truly sad, i have to beg him on the daily, and even then hes alwaya 'too tired' or 'not in the mood'. But hes plenty in the mood to watch porn every night. He even has it bookmarked on his phone! I understand that it can be healthy, and a sort of alone time, but i feel like to be considered healthy he should have a desire for me too.

Its been an issue for awhile, and to prove to myself i wasnt crazy i started charting our sex. Average: twice... a month. And each time it is my idea, qnd its so generic and quick, its like he is just worried about getting it over with. When its done, he gets up, puts on pants, and goes to the living room to watch football. Yet the internet history has him visiting multiple porn sites a day... a DAY (i am actually baffled where he finds the time).

Have i done something wrong? Am i making a mistake by hoping he will marry me? Should i be concerned about his health?

To clarify, we are 23 and i have remained the same level of attractivness.
