Topical gels are growing in popularity for many men. These gels are applied to the penisand the skin absorbs the contents of the gel before sexual activity. While promoted as a safer alternative, these gels can still cause an allergic reaction or damage to the reproductive organs of both partners. It is generally a good idea to research a gel in advance and determine the overall effectiveness and safety prior to application. When possible, test a small amount on a tip of your finger and your partner’s finger to avoid causing an allergic reaction in a sensitive area.
