What are some sperm-friendly lubricants?
Most lubricants will kill off some sperm so it is best to use as little as possible. It is reasonable to use a small amount of over-the-counter brands such as Astroglide, or ask your doctor to order you some FemGlide. Saliva is not a sperm-friendly medium, nor is water. Anything petroleum-based, such as Vaseline, should be avoided.
