So... full disclosure, Jamie is basically me in college. There is a LOT of sex you can have without running the risk of possibly getting pregnant, and I did about 50% of it in my early twenties.
And I highly recommend it!!
Just FYI, kids: sex is a pretty flexible term, and it's not a big deal. Oral sex, manual sex, mutual masturbation, French kissing, groping, holding hands... dude, whatever you wanna consider "sex," consider it sex. I guarantee your friends are. ;) Let yourself choose your boundaries. I did, and I don't regret a single year of it.
Here's the old black-and-white strip, which was just as encouraging of Your Own Version Of Sex as this blog post is today. :)
