Orgasm question

Ka

So I was wondering if I'm the i my one or if this is normal. So before I have sex i always have to go pee before just because when I am having sex and I'm about to have my climax i have a difficult time having my orgasm if i don't go pee first. So I am not sure if it's just me or if this is normal. Even though I don't have the urge to pee but I have to try before I have sex.
