Sorry water based LUBE, not vibe...
The water based vibe is smooth to the touch, we are just worried that it may cause microscopic scratches. It is a beautiful lube otherwise (and we paid close to $500 for it!)
Hello,
If there are any course particles, then chances are there that it can cause friction rub of the thin and delicate areas of penis and vagina. For a lubricants, water based lubricants are the best. It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
