Is it really normal for a 23 year old to get so many crushes? Or am i really a mess?

Yesterday I shared about this girl in this excel class who sat next to me as she didn't have her own laptop so she told me to share my laptop with her. She is 22 or 23 and I also turned 23 a bit over a month ago. I had got almost an instant crush on her as she is really pretty but suddenly overheard her saying to her friends about her boyfriend so i felt terrible. Today I again got an instant crush on yet another class in the institute where i go for preparation of some exams to get into an MBA B School as I still have 2 more exams to give. This girl is in another classroom so we don't even know each other and she is also like 22 or 23. She is like one of the prettiest girl i have ever seen. But as usual i am shy near girls in person so was too shy to talk to her. I told my friends and they were telling to go to her and talk but i was shy. I came to know her name as i heard her friends calling her by her name. Luckily i found her Instagram profile too and will follow her and maybe message her after 2-3 days. I have no idea whether she is even single tho as she is so pretty that its very much likely that she has a boyfriend too. You also know about this girl Anshika about whom I posted before. She also just turned 23 over a week ago and i still like her. But she hasnt been to class yet as she was in her hometown and hopefully i will meet her on Monday. I also like this girl who is 19 turning 20 in April about whom I posted before and we chat on Instagram daily since July 2023. We were in same school but didnt know each other in our school days and we too are planning to meet up to eat somewhere this month. So in short, i crush on every beautiful girls i see who are in the age range of 19-28. Is it normal for a 23 year old like me to get frequent crushes or am I too old for that and its pathetic?
