obviously i can't give you an exact answer since i don't know the ingredients in that body lotion. i am guessing that it had some type of menthol or other chemical that resulted in some numbness. i do suspect this is temporary and that your penis will return to normal soon. needless to say i hope you washed it off as soon as it became numb. depends. you might have caused some real damage. what you should use is a penis health creme called man1 man oil. it contains the amino acid acetyl l carnitine that restores lost penile sensitivity. it's totally safe and used by a lot of guys all over the world. hope this helps.
my penis has felt numb since i used a body lotion as a lubricant on it. when will it return to full sensitivity?
