Dude, hear me out, it's perfectly normal to worry about your feelings or the way you feel, overall if we're talking about this area in specific, and it may become the source of a bunch of headaches, but one thing is clear: you're not finished.
Don't misunderstand me, what I really mean is that you're still growing and forming your mental patterns in every conceivable way of the concept, so don't be scared about ending up alone because, knowing you, you won't, just don't rush it, maybe your body, both physical and mentally doesn't consider itself ready to "love" someone in a romantic sense, and that's nothing to feel guilty about tho, simply everything at its time, then take it easy enjoy and you'll see how Cupid resurrects even sooner than you imagine
