Maybe my viewpoint is lopsided, but being almost 20 and never having experienced real (real is the operating word here) romance or physical attraction or been in any kind of romantic relationship at all, I'd say the ups and downs are collectively a better thing to have than the monotony of never having done any of it. Seriously, my life is boring as balls. I'm not hunting for people because a) I have impossible standards I never expect a real human being to actually meet and b)I know frantically searching for a partner to latch onto like most people do is the most surefire way to create a brief, unstable, and unsatisfying relationship. Either I'll stumble across the love of my life or go forever without him/her/it, but I'm not going to jump in the fray with a pickup line and a searchlight. That's foolishness.
