Tried using poppers at one time... could get the most amazing floppy dick you could wish for, had orgasms that were out of this world with cum flowing freely!!
Great fun...............For a limited time.
Don't know if will work for all,and not recommending anyway, just personnal experiance.
Has anyone tried "Monk's pepper" read aout it resently monks of old used it to suppress erections..... sounds interesting (available on Amazon I see.).
