Odd taste

Ladies! Please can you help?! I gave my boyfriend a blowjob which he loved & then he went to return the favour. However, when he got down to my.... He said that it tasted funny and couldn't do it, I've never been so embarrassed! Does anyone have any tips on how to make it taste better down there? I shower everyday and have tried to switch shower gels but it doesn't seem to work 😁
