And there is absolutely nothing wrong with being a late-bloomer, or in delaying romance and sex until you meet the right person or feel ready.
I know it’s a bummer to get crushes on people who are already coupled up, but you are sparking with people!
It is unlikely, being as self-aware as you are now, that you will repeat those same mistakes.
So I’m a guy, 20 years old and totally devoid of any form of romantic relationship. I’ve never so much as held hands with a member of the opposite sex, never mind anything else.
I’m getting incredibly lonely and yes before you say it, I did behave like a nice guy tm once and just once.
Even though the story took place downtown in a major city, there were no other women in the frame, though the character did frequently interact with men of all ages & walks of life. You say that not many people are interested in your passions.
This is true of the Hollywood world, too, where there aren’t even enough women in crowd scenes. You need shy people who are trying to connect with each other and the sexiest/awkwardest dance to The Commodores’ Night Shift in recorded history. Have you looked all around your university community, or your dorm, or your study program?
