Suggest A Cream To Keep The Vagina Dry

I am a retired ED RN and am fairly certain of my dx of cherry hemiamoas on my labia majora. We are "snowbirds" and recently changed our insurance plan which does not kick in until Jan 1st. so I would prefer not going to the doctor until after that date. However, I have 3 of these that do build up in pressure and sometimes bleed a scant amt into my underwear. Is there anything I can put on these topically to dry them up? And did I get these by beginning an walking exercise program recently?
