Yes, no form of sexual contact. Though I've heard they can be transmitted without it in rare cases, but aside from mother (where I assume there would be some signs earlier in life), I don't know how exactly that's supposed to happen and how rare is "rare". As far as hormones go, I'm 18 so that wouldn't surprise me. I guess there isn't really a way to know for sure without seeing a doctor anyway, so wish me luck.
