I instantly have, a crush on a guy, I just met ;-; ...

Honestly I'm gay... it's not surprising but, lately I went to a BBQ w. My sister and her boyfriends family, and I find the boy cute (Btw before you think I'm a creep WE ARE NOT RELATED DIFFRENT BLOOD LINE NO BLOOD CONNECTED) I never met him before since I'm not even related to him, I liked his haircut he just seemed cool. I am shy like really shy... it's not good but meh... They went in the hot tub and I went in after a while of self deprivation XD I went in just being quiet in a corner, he talked to me a bit but not really focused on me... I just told my sister I was having a mental breakdown 🤣🙃😝☺️😙😉😙🤣😄😗 help me... But he looked really good he was only one year older too, He was fit too, his name was Joshua. After a while we ended up playing with his sister and we became friends.. I was happy it was fun, I really liked him then after a while close to before I left I liked him in a romantic way XD... I'm not a romantic person, I'm a god damn kid!!! Well kinda, he is fit (I am too every hour 50 Push ups) I liked him... I don't know if he is straight or not, but I haven't told anyone I'm gay... I'm telling on this cuz I probably won't see any of you in my life ever... people have said don't fall in love with a straight guy.. but it was kinda at first it happened, that's never happened to me, he lived in the same town I do like 10 minutes drive away. I'm planning to meet up and after a while and go out.I miss him and I only knew him for one day... if you have any experiences with this please let me know it will help..
