First time with a guy

I mtf recently just had my first ever time w a guy! I’ve been “out” for about 2 years and i defo pass as a girl. Wellll i was touring a college id like to go to about 3 months ago ish, they had this little portion for us to walk around by ourselves for ab a hour. Maybe like 10 min in this guy came up to me and introduced himself, he was a junior and saw me with the tour and asked if he could show me around. I said yes obv and we used the rest of the hour just walking, i ended up skipping the rest of the tour and i just went back to his apt. It was there i let him know i was trans and he was actually rly nice ab it! We hung out the rest of the day and have a couple times a week over the past couple months. I was at his apt last week watching a movie n a girl was naked in it and my friend got visibly hard, i called him out for it and teased him a bit and he got kinda flustered. Obv i apologized and then told him i was too (i wasn’t but i wanted to make him feel better lol) he was dead serious n said prove it. I was like wtf and thought he was joking obv but then he asked again n said he was serious. I was like no at first but then i ended up doing it n it kinda just went from there
