hey guys
i'm 18 and i think i have a fairly small penis
i ahve a problem with premature ejaculation
my penis is so small i think that it barely enters and rubs the inside walls on the head only?

i usually last about 20 seconds to a minute with my gf
i have tried stud 100 desensitizing spray
and condoms with climax control lubricant.

its killing my sex life and making me depressed.
are there any meds i can get to help me with this?
i dont want to be terrified of sex my whole life
