How do you make yourself smell better down there?

So I love head, like what girl doesn’t? But the problem is...I’m very self conscious about how I smell down there, and my ex-boyfriend used to make a lot of rude comments about it when we were together and ended breaking up for different reasons later on. Any ways ever since I got with my new boyfriend (we’ve been together for a year now) I’ve never wanted him to go down on me because I’m scared he’ll have the same reaction. And I mean I want him to do it really bad, my ex would do it all the time even tho he did make comments, but I just don’t want my now boyfriend to say those things. He is always telling me how he would love to give me head but if he ever goes near down there with his face or hands I push him away, and I’m the one just giving him head all the time and then having sex.

I just really want to know how to make my vagina smell better so I have more confidence and we can do other things in bed then the usual. I don’t eat very well and I feel like that might be the issue, but I do drink lots of water, actually that’s really the only drink I drink lol. But I just wanted some people opinions on what I should do?
