why i feel like i wasted my youth w serious relationships?

hello im 24/M and my bf M/25 . i had 2 boyfriends last 5 years w my ex 2021-2023 and with my current bf 2023-still. I’ve never EVER cheated any of them and never desired another man(as i should ik!!). But the case is now im realizing i was too young to be in such serious relationships. Dont get me wrong they were not bad people but i missed many activities etc. Mostly i avoided going out w my friends. I never wanted to sleep around NO THATS NOT WHAT I MEAN. But i wanted to dance ,have fun ,maybe have crushing over some pretty boys. My friends always ask me about relationship advice but i cant give them ive never chased or flirted w my bfs. They found me and directly we got into serious relationships. One more thing both my ex and my current boyfriend are not financially comfortable as me. I never had any financial problems thanks to my dad maybe thats why i never care about money. My ex was receptionist at some motel and i was ok w that. I lowered my holiday standards etc. While i was with my ex many people try to get me. I remember one guy his dad owned a hospital and he was always trying to talk to me, pulling up to my house w his g wagon but i was all over my receptionist bf. AND LET ME TELL YOU he was not even my type! i simply was in a relationship w him because he was kind and he was loving me too much. For my current bf he is also kind person, respectful and thankfully kinda my type. But thats it. I do some commercial modeling and im also last year med student. Im tall, bronde, green eyes , athletic. My dad has some business. I dont know why i went for only personality and wasted my years. Looking back i realize i wasted all my summers cuz they needed to work or they simply couldnt afford so i was w them during summers. Many model like rich guys try to flirt me but i turned them all down and for what!! I dont know i guess i read too many love stories when i was little and tried to romanticize everything!
i know its a sensitive topic and i feel terrible for writing all that out loud but i cant stop feeling the way i feel..
i love my current bf and he loves me too but what if 40 years old me look back and regret my decisions..
