With a 22 year old.
Stupid, yes. Was I talked into it? No. I made the choice on my own.
To this day, my parents don't know. They think my now husband was my first and only.
To this day, I freak out when I have any kind of blood testing done. Thinking that some uncurable STD is going to just appear because of my romp in the bedroom as a stupid teenager. I know, after all this time, I should be relaxed about it and that it's unlikely, but I've heard cases of HPV and herpes not showing up until years after exposure.
Believe me, I plan on being very open, honest, and stern when teaching my kids the impotance of safe sex.
