My friend have kidney failure is it ok to have inter course with him im scared will i get sick from the toxic smell
I would think you'd be more concerned about his health then having sex with him and any odor. Hope he gets help soon.
You may want to consider if he's healthy enough to engage in intercourse and also if you are strong enough emotionally to physically be intimate with someone who you are finding yourself sexually repulsed by. There is no danger to you.
Go on ahead.
