Sta-Hard cream is a desensitizing lubricant intended to help prevent premature ejaculation.
Of course, we can think of a few other fun reasons to desensitize your partner.... The amusing directions on the box suggest applying the cream and waiting a few minutes "...before having marital relations." In general we recommend following product directions carefully, but we don't think you necessarily have to run out and get married before using this handy product.
Please note that this cream is oil-based, so unfortunately it is NOT compatible with condoms. Approximately ½ ounce.
