Boyfriend wants to eat my pussy but I'm pretty sure I've got BV or a UTI or whatever

I'm 17, boyfriend is 17 too. We've had sex before but I've never let him go down on me because I'm pretty sure I have some vaginal issues. I use boric acid suppositories and they help for a while but my issues are reoccurring. Dryness, odor, sometimes irritation after I pee. My boyfriend wants to eat me out and i want him to so bad but I'm hesitant because of my problems. I can't get anyone to take me to a gynecologist. Every time I talk to my mom about it she's just like "Oh you should just do this or that" so yeah. Not sure what to do,
