What is this smell?

Past few hook ups smell a bit off?

My ex has zero smell down there, could eat it out for half an hour and it still wouldn’t smell anything other than like my spit, we broke up a couple of months ago and the past 4/5 woman I’ve had sex with have an unbearable pussy smell? Like it’s still on my hands after we had sex an hour ago? I couldn’t imagine even attempting to eat them out

What is going on? Why does some pussy stink?
