Pre-seed lubricant

Dess
Id like to get feedback from anyone that has used the pre-seed lubricant. I am planning on getting it but only if i get good positive feedback. Id like to know though how long you used the product. How long did it take for you to conceive once you started using it. How often you used it. Really just as much info as possible. And the biggest question would you recommend this product to your child (when that child would be of age and all that).   Thanks guys
