You can't go wrong with a high-quality silicone lube in a very convenient pumped up bottle! 

This paraben-free, FDA-approved formula enhances the ease and comfort of intimate sexual activity with long-lasting lubrication. This hypoallergenic formula is odorless and non-sticky and is compatible with condoms and can be used underwater. Reapply as desired. Do not use with silicone toys. It can be used with condoms.

Shine silicone is pH-neutral and does not effect vaginal pH. Unlike shine organic or heat, shine silicone does not contain water and is therefore considered pH-neutral rather than pH-balanced.
