We find the majority of our customers with LS seem to prefer YES OB plant oil based as it is a richly soothing emollient and can be used on a daily basis and during intercourse (not with condoms though). YES WB water based is more suitable for intercourse but some sufferers use it for daily moisture and comfort as well. If you are being treated with a steroid cream then it would be best to leave 12 hours between applying the YES oil based and the steroid, as the oil could act as a barrier. YES water based will be quite quickly absorbed so the time between applying it and the steroid cream could be much shorter.

If you are using dilators or adult toys to aid sexual intercourse, both YES oil and water based are safe to use with these aids.
