i have tried many retaining semen and delay talismans from this site ,
my exprience to be honest : many of them worked but there is always a timing for about 1 to 2 hours of ejeculation and you cant hold it more then 2.5 hours otherwise you might get genital swelling or pain

this one does not work on me
the most successfull method to delay 👇
say 3 times ینتروش
during intercouse and you will last for 1 hour or more
