Oh I have lost some things.
When I was in my 30s I was a self absorbed ->-bleeped-<- that likely would have cheated if it had been offered.
I'm glad that swine didn't live through the 90s and my sort of death that fybromyalgia inflicted on me (I have basically come to regard my life as having ended around 97 I died inside thanks to the outside failing).
Fate simply never gave that other person the chance. I dodged a bullet.
Recently, my evolution into my awareness of being female has made some of my preferences shift. Not sexual preferences, I am talking about my hobbies. My wargames, they just don't have the same aspect any more. I've chatted a lot about it. There is a reason why there are not a lot of female wargamers. There's no point trying to make girls like wargames. There's also no point trying to have equal numbers of male and female English and Math teachers in a region.
I have lost some of the fear of the things I like, I just thought were wrong. I spent a lot of years resisting liking baking. I'm old fashioned deal with it, a woman belongs in the kitchen

Well, now, I can look at my kitchen from my hobby room which is basically the same spot, and laugh knowing I have belonged here all along

I used to think I was such a 'cool clever guy' for being able to iron and sew and enjoy so many things so many guys wouldn't be got dead liking openly. And now I find, I am merely ok with it for the obvious reason I just feel like I belong.
I don't want to drink beer and belch with the guys while watching 'the game' on TV. I'd rather go to a Tupperware party.
Hey I am not saying girls can't like sports, but sports does nothing for me at all, and now it doesn't really bother me.
I didn't want to be like my brother and be on the football team. I suppose I'd have been happier being a cheerleader

I was just today laughing with a friend over my increasingly lousy gaming performance, I told him in reply to a comment of his, I'd warn him if he started looking cute

I have lost my worry about playing me in a role game.
I've lost my need to explain why I am crying while watching anime romances.
I haven't lost anything valuable. I've lost a lot of junk from my life though.
