Please help

I want to have sex with my boyfriend and I'm sure he wants to too but I am scared. My urine has been smelling weird and sweet and I dont want him to know about that. Bt if we sleep together he might find out. I don't know why my urine has been smelling this way. I am a very clean person and  I have not have sex with anybody besided my boyfriend, he has not slept with anybody else either. Is it normal that my urine smells this way? Is like a sweet strong smell
