Lichen Sclerosus is a skin condition that should always be diagnosed and treated by a medical professional. It is frequently misdiagnosed as thrush, so if you have been told you have thrush and have white patches and thinning of the skin (itchy or not) on and around your genitals, you may want to look for a specialist.
Treatments have generally included steroidal cream on the affected area, and more recently, multi-week antibiotic treatment. For some who have Lichen Sclerosus, sexual activity in, on, and around the vaginal and anal areas can be painful.
Additionally, check with your medical professional about what type of sexual activity you are cleared for; if you are using a steroidal cream or similar treatment, you may need to wait until the end of your treatment. If you are cleared for genital sexual activity, using lube is always important to keep your vaginal and anal tissue happy and healthy.
Silicone-based lubricant lasts a little longer, so it might be a good option if you want something to stay slippery. If you prefer water-based lube, going for an organic and/or all-natural variety is a better choice as you will be less likely to react to any of the ingredients in the lubricant.
On the other hand, if sexual activity around the genitals is painful to you, you can do lots of other sexual and intimate things. Sensual and intimate massages with oil-based lubricant and/or oil-based massage oil.
The National Vulvodynia Association supports women with Lichen Sclerosus who are struggling with thought, feelings, and actions around their sexual identity in response to the disease.
