"Eroxon is supplied in a single dose tube. When to use: Apply the gel just before sex. How to open the tube: Unscrew the cap. Pierce the tube seal with the top of the cap. Squeeze tube firmly to empty all the contents which will provide the correct dose (approximately a pea-sized amount of gel). How much to apply: Apply the contents of one tube to the head of your penis. How to apply: If you are uncircumcised, gently pull your foreskin back as far as comfortable before applying the gel. Massage the gel onto the head of your penis for about 15 seconds. You can apply the gel yourself or your partner can apply the gel as part of foreplay. Eroxon will only help you get an erection if you are sexually aroused. You and your partner should engage in foreplay just as you would if you were not using a treatment for erectile dysfunction."
