I don’t know how to cuume or mastebate

So for some reason I feel like I don’t have a clit Cause I can never see it or feel it and I can never cume when I master bate and when I do master bate I got no juices or wetness to be seen it’s just clear dry gunkie goo. I only just started recently master bating and learning For the past year and when I have had a orgsam it feels like nothin. Like I came with 2 different blokes and didn’t even notice even tho there was a massive wet spot on my sheets I just denied that I came cause I didn’t get the big amazing effect like everyone it just felt like eh. Also I use to master bate when I was very little when I was asleep so I also think I’ve over used my clit and that’s why it’s so numb like I put a vibrator on it and yeah it feels good for a few secs then poof the feeling is gone. Any ideas on why my clit gotta be numb and why and when I orgsam it just feels nothing great and how I can cume ? How do I masterbate as well ?
