Douching...?

Raquel
Alright so I keep going back and fourth on this subject. I've done a decent amount of research on it and everyone says it's not good to do. 
My vag is very sensitive as it is, I'm prone to getting urinary track infections/yeast infections, so I've never tried it.
..but my boyfriend wants me to start douching. The other night we were watching Amy Schumer: The Leather Special and she jokes about oral sex a lot. So my boyfriend and I got to talking about it and he was saying how much grosser going down on a girl is bc it stinks the entire time. He really made me feel like shit about myself because apparently I have an odor that he doesn't like so he won't go down on me
I shower every day when I get home from work, I'm very clean. I wouldn't even let him near me if I didn't feel completely clean. I've never smelt another pussy but I feel like mine is normal. I don't even ask him to go down on me because I know he doesn't want to. I'd love for him to but I'll never enjoy it now. It's frustrating because I give him head all the time. I'm debating whether not I should just try it.
Is there anything else the would take away the order?
I've heard pineapple makes a difference
