My boyfriend and I were messing around and he had fingered me (says he is sure no pre-*** was on his hand, I am fairly sure as well) then we did some dryp humping, with my underwear on. I am on the pill but I miss it sometimes, I don't think I had missed one in the last week (my brochure says even if you miss one you don't need backup) and he never ejaculated but I am still scared. What is the risk?
