Had my first kiss at 22, feel mostly positive about it, did I do the right thing?

so long story short, I'm a uni student who has been trying to get more in touch with my sexuality for the last 3 years (I'm bi, haven't done any) so I downloaded Grindr and started looking.

so yesterday I was waiting for a class to start and my phone started ringing and a guy was messaging me wanting to meet up, most of the time I would just ignore it but I felt like I should just go for it.

we started chatting and it turn out he was at a bus stop nearby, he asked me for d and face pics and didn't block me (Which is odd, I'm on the smaller side/ not a looker) I suggested we should meet and he agreed, I left my bag with a friend. So while I was going my heart was mad pounding until I got there.

he wasn't like my type at all but I was so excited for my first time meeting a person who knows I like dudes too that I sat down with him and we started talking about things, I told him I haven't even held hands with a guy before and he laughed, like in playful way.

next I know, we talking about doing things, he told me that if we had more time he would've liked to take my v card and for me to fuck him and I was hard as a brick and blushing like hell, then he said that there wasn't time or a place to do it, so he suggested blowing me.

by then, my class was halfway through so I told him I couldn't and apologized, he understood and told me that if I would be ok if he kissed me and I said yes quickly of course. so we went to a semi secluded spot and he approached me and kissed me, it felt like both an alcohol and nicotine high that wouldn't go away, I felt dizzy but happy. then we heard some steps and we stopped. then the people left and we resumed, his tongue felt so soft but so demanding at the same time.

we parted ways and he asked when I had classes again, as he wished to meet again. the whole walk to my classroom I couldn't really register what was going on lmao and didn't pay much attention to whatever was going on there. when I got home I felt anxiety stomach aches probably from the adrenaline.

he texted me and asked me if I wanted to fuck him and I said that I would love to, but then the post kiss clarity hit and I remember both that I did that at the University and that I really can't afford to come out of the closet or want to. so I explained to him that it was a nice experience, we should just part ways forever and he took it well.

did I do the right thing?
