I Currently Have Several Plantar Warts On Both Feet. I

I currently have several plantar warts on both feet. I went to a podiatrist and she perscribed Fluorouracil Topical Cream USP 5% to use on them for 12 hours then wash and then place some salalytic acid patches over them for 24 hours. My question is, I just read that I should avoid having sex while using Fluorouracil. I'm not on chemo or anything. Does this not apply to me?
