Can you make bjs taste good?

I’m posting for a little advice.

My wife is a bit of a gagger when it comes to BJs. It’s not from the action, she says it’s the taste that makes her gag. At present she only blows me in the shower as the water lessens the taste.

So I wanna know is there anything I can do the help with the taste?

I’m a clean man who washes thoroughly(no DkCh on this boy!), I’ve changed soaps a few times just in case and I don’t eat anything unusual. I’m a little bit lost here caz she loves to do it but can’t get past the taste
