Undescended testicle

I had surgery to bring it down when I was 6 and was told it would come down as I grow up. I'm 18 now and it sill hadn't so I went to see a doctor and as it turns out surgery is highly unlikely to work at my stage of development and the doctor even suggested removing it completely to eliminate cancer risk and putting in an implant, but I really don't want to be the kind of guy who's so insecure he gets a rubber god damn ball. I looked into this a bit more. So 4% of male babies are born with an undescended testicle but it descends by itself in the first year of life. A small percentage of those 4% (me) need surgery after. And surgery is successful most of the time. So I'm in those 0.000001% unlucky men. As you might imagine, this has got me even more depressed than usual, I don't deserve to be a monoball. Anyway, has anyone else maybe been in the same situation or know someone with one testicle?
Thanks

P.S. it's fine physically to have one ball, but I'm not too keen on explaining to women why I have one ball in my ballsack, bit of a mood killer I think.

First, don't think this has anything to do with deserving something. Shit happens. Some of us have a testicle that doesn't descend and others are born into poverty in North Korea. Which would you choose??? Now think about the guy whose testicle doesn't descend and he lives in North Korea!!!! You have and all of us have it pretty good from that point of view, lol.

I had a friend who had that surgery and implant done when he was 14 or 15. He was A-ok after it. I assume girls can't tell it is an implant b/c he would have told me if a girl was blowing him and licking his balls and said to him that one felt funny lol.

Go with the implant. After you heal up and a girl licks your balls and notices nothing you will completely forget about it.

if you feel insecure about having one ball I would go for the implant. I mean no one would notice and it would give you confidence. I know of one guy who had an implant and he had a perfectly normal sex life. Have you lost any sensitivity in the testicle that remains?
