the only thing I can catch these days is a virus. I actually had to get an HIV and hepatitis test before my wedding. I have never been as nervous in my life as when the nurse opened the envelope with my results.
I'm not a smack head so that side of things isn't an issue but when you start thinking back every sexual partner you ever had and then factor in their ex partners, then theirs,then theirs, etc, etc, it gets to be pretty fuckin scary, I came out of there feeling like I'd won the lottery
