Warning for perhaps a little bit of mature content down the road.
So here's the story: last weekend, I was at a party and met this girl, Kristen, and we had sex. By 2am we had ended up in bed together. We were kissing and it became clear it was headed a certain way. She kept trying to reach for my crotch but I moved her hand away, I panicked and told her I didn't have a condom and that I would just like to perform oral on her, which she seemed more than fine with lol. I had assumed it would just be a one time thing, but the next morning she seemed pretty interested in at least having sex regularly or even being in a relationship. She invited me to her birthday party, which is next week as I write this.
The issue is, she has no idea I'm trans. We only met that night, and no one else at the party knew I was trans either. She is straight, she told me, and made a comment earlier in the night about 'liking dick'. Which I don't have.
I think I actually like her, but I'm sure the next time I see her she'll want more than last time and I haven't had 'the conversation' with her yet. What should I do? Wait until the moment and tell her? Try contact her before hand? Or just end it there and not really pursue a relationship so she can keep thinking I'm cis?
