Am I a horrible person?

I was at a party a couple days ago and we all got a little drunk and I ended up really hitting it off with this girl, stations were great with the topic of me being trans was never able to come up, later on, we separated to play group games for a bit and she ended up getting more drunk and trying to hook up, we didn’t fully hook up but she did give me a “blowjob” in the bathroom. I have a reelmagik. so yay points for realism. but also how the fuck do I tell her
