Hey guys thanks so much for all your advice.
I will try to explain better -
I only do massage service but do oral without usually. Where I am in England there are not many girls who offer this service and I am qualified masseuse so it usually works quite well for me. I cannot do sex because my boyfriend is not comfortable with it. He was comfortable with the risk of OWO.
I feel that reducing my services even further will result in a drop in income I can't afford

, but due to my health and my boyfriend's health I would not do OWO whilst I have an active ulcer as it's like a wound in the mouth. Don't do CIM but even the risk of pre-cum going near the ulcer would FREAK ME OUT!
I could easily do Oral With however the ulcers get really sore and multiple OW a day would really sting and hurt too much with the friction )-:
I think I am gonna have to just drop my services to Massage and hand Relief and take the drop in income this will cause. At least whilst I have an ulcer.
Re the underling cause I'm not sure what it is. The ulcers run in my family but before I got this damned kidney problem I only had the occasional one. Since I have been diagnosed with the kidney problem my sleep has been very bad I can't sleep often so am probably run down which could be the cause. Although I eat as healthily as I can loads of veggies etc, I have to stick to a special diet to prevent kidney stones developing. No dark leafy greens allowed or citrus fruits at all , or vit C tabs so maybe that is the cause too? Maybe I should consult a nutritionist to see how I can get my allowance of Vit C without going off my diet and risking more kidney stones?
I have been tested for anaemia about a month ago and my iron levels are good they said.
Thanks so much for all your advice I will try the mouthwash bought some today and also the salt water rinse.
I think I am going to stop all oral and just do hand relief service (less money

) for now and see if I can see a doctor / nutritionist to see if they can give me anything or advice to improve things.
