Have Sex

I've been getting mistaken for a guy by mostly everyone. So in my college, for a year there's a set up for online classes so my my class haven't met me or haven't seen my face, they only know my name and my voice. My voice is naturally deep and everyone just assumes I was guy. Not until the graduation, I showed up. They were looking for one classmate who they thought was a guy, I told them I was that person they were looking they were surprised I was a girl the entire time. They saw how long my hair and my body doesn't scream a boy at all.

Guys tell.me how should I convince my boyfriend to get pegged by me. Give me some tips.
