Bf and sex

Oh man 😓 these days i just dont feel like having sexual relation.. and its like it hurts or feel uncomfortable when we do it... my bf needs it and its the first time he tells me that hes going to masturbate in the room alone cause i dont want to do it ....

I mean its fine , he can do it . I just feel bad cause i dont have desire to do it anymore ( well so far) 😥 now he thinks i dont love him as much.. i tell him no that i love him its just u know it burns and feel weird in a bad way i guess 😣 what do i do next 😔
