Why does my girly juice taste bitter?

I'm very hygienic & have never had an odor issue down there, I always stay neatly trim or shaven when I plan to have a bit of fun ;), and I'm up to date on my reg gyno appt's. I've never had an infection or anything along that line. So could this bitter taste be due to my diet? I do eat a lot of red meat and I've heard that could contribute to the issue. I've tried drinking pineapple juice... doesn't work too well. It makes my urine smell a bit strong and I'm not about to go vegatarian even though I've heard vegans taste sweet. What do you guys think would help? Anyone else have this issue?
