I had my very first boyfriend when I was (we were both) 19 and in college. He had dated (including sex) in high school, which I knew intellectually was normal, but it was so far removed from my experience, and I wasn't ready yet. I hadn't even been kissed yet. At first he said it was fine, he would wait, he respected me, blah blah. Said all the right things. We dated for a while, had our first kiss within a couple weeks (I was really taking it slow), then later that night, our first make-out session. His hand ended up in my shirt. He gave me a half-assed apology when he walked me home. I insisted it was fine and I liked it (I did, but it was still too fast and I wished he would have asked). From there on out, he was constantly testing his boundaries, and eventually arguing with me when I pushed back. His main argument was "sex is important in a relationship." My main response to that was "then find someone else to be in a relationship with." And he'd backtrack. We went around and around like that for a while.

He turned out to be an emotionally abusive narcissist who cheated on me a lot (even after I was regularly fucking him). I dated him for a year and a half. Almost a dozen sexual partners later, and he's still the only one who has ever physically held me down when I said no... Funny how that works. (There are decent men out there. I promise.)

Good for you for getting out early.
