Cultural Relationship Problem?

I am 20 years old, Spanish guy of course ^^ and I've been dating an awesome Bangladesh girl, 19 years old. Our relationship very outgoing, we have a great communication, we can talk about anything. We've been dating for 6 months so far, but lately there's 1 single thing that bothers me and I can't deny it any more. I wish I could tell her, but she's just toooo and sooooo effin adorable, by just looking into her eyes... I just can't tell her this... T_T... it breaks my heart, I feel I'm going to hurt her feelings, but I don't blame her ;( I don't know how to ask..., or in what way should I ask her this... is it.. a "why" question, or just like "look babe, u just *******************".. I don't know what to do, its just a problem that affects my family too, since she comes to my house and sits with us at the table or something, and we go out to places and I just can't no more =\ sometimes it bothers me, and I just have to hang around really close to her so I can get used to it and forget about it, but sometimes I can't. Look the problem is that her odor is very strong, I know she showers and everything she has a good hygiene but.. how can I stop this? should I ask her why she smells like that? tell her what's the problem straight up like "hey baby the problem is that... you sorta have a strong odor like if you don't shower" or something like that ;( help!
