Trudging round Tesco with my oxygen cylinder and my 91 year old father in tow yesterday, I decided to look for KY Jelly based on recommendations on this site. Being on oxygen 24/7 and taking warfarin due to recurrent PE and DVT's, I suffer from horrendous nasal crusting, which is often bloody and painful and regularly blocks my passages so I'm struggling to breathe, so I'm prepared to try anything. However I don't know where to look for it so after a sweep of all the likely aisles I decide to ask at their pharmacy counter, where 2 young women appear to be discussing their plans for getting plastered after work, and when asked "Do you sell KY jelly?", one of them tries to supress a cheeky grin. An older supervisor type guy sees my confused reaction and says they haven't got any in the pharmacy but kindly offers to fetch me a tube from within the shop. I thank him and think no more of it until I get home and after a big battle to unpack the shopping I collapse back into my recliner and look for the instructions for this jelly. There is no leaflet but the box explains it's to alleviate vaginal dryness and help to maximise comfort during sex. I thought at first I had been given the wrong product, but further research confirmed its use instead of Vaseline for O2 users, and I have to say it appears to be working well. No wonder those young women were giggling. I think I must have had a sheltered upbringing.
