Experiment (for science) on the taste of cum

Did this experiment with my wife. Same for men also. A whole week my wife and I ate more fruit than normal. Especially pineapple because of sweet tasting juice supposedly. We had sex everyday. Not alot of foreplay other than petting each other. After 7 days of eating alot of fruit and a normal routine each day we performed oral sex on each other. Her vagina tasted sweet and somewhat salty. Nothing crazy but it was great. My cum tasted sweet she said. The next week we didn’t have fruit at all. Meat and veggies and carbs. Same thing all week and 7th day we did oral and too my surprise her vagina was not sweet at all and more tart salty and meaty tasting. My cum she spit right out. Said it tasted horrible.
