Not sure about the other bros here but the worst experience is you bonk the FL and when you pull out your dick from the pussy to change position, you smell a strong fishy odour. Really kills your erection...
Of the girls I tried, local FLs have the most frequent chance of having that fishy odour. Asked some of them if they think something is wrong and they don't even know fishy odour in the pussy means bacterial infection
That said the remaining 50% are okay
