My farts smell like lavender and rosemary

I know it sounds like a joke but they really do, it's not a new thing, been this way for years.

I almost think half the reason my gf doesn't dump me is because of how my farts freshen up the house. We make jokes about it all the time, because they really do have an uncanny resemblance to lavender/ rosemary. I do eat really healthy and it got me wondering could there be a connection? is it normal to have farts that smell good? Could this be a medical issue?
