I don't know if the latter is entirely true. I certainly feel like I've missed out on something in life. I'm probably guilty of idealizing what the ideal relationship would be but it's hard not to when you see others who seem to have achieved what I desire.
For me personally I am terrible with social skills and always extremely anxious/nervous when talking casually to strangers, especially women, not that there are many opportunities to talk to them casually for me. I can never think of what to say quickly enough for there not to be awkward silences and I wouldn't even dare think of trying to flirt. I don't think I lack emotion but I do strive to hide it irl.
Dating apps aren't much good for guys unless you're one of the desirable ones and I don't think many would view me as desirable. Dating apps also seem to attract certain type of people, I'm not certain how I would describe it but I just don't see the sort of people I can really relate to.
