 [ Symptoms ] my penis has felt numb since i used a body lotion as a lubricant on it when will it return to full sensitivity [ Disease ] obviously i can not give you an exact answer since i do not 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 is totally safe and used by a lot of guys all over the world hope this helps
