@anon2016,
So why the hell did you come here with this topic? You wanted input, and you got it. Not my issue if you didn't like what you heard.
You knew what you were going to do, and nothing was going to change your mind.
Which btw, I wasn't telling you or anyone what to do, just what the consequences are bound to be.
I didn't automatically jump from 8 months to 22 years you know. We kept parts of our past private back then too, obviously. Plus, it wasn't our first rodeo for either of us. We married when I was 34, and him46. We both had a lot more milage on us than you do. Both been there, done that with the sharing everything, had learned that's sometimes not a good policy.
What's wrong with wanting to know something just out of curiosity? Ever heard of the expression "curiosity killed the cat"? Being curious is a fine attribute. I'm curious about a lot of things. But I know when to temper it with common sense. It's not a matter of comfort, it's a matter of what's going to keep a relationship that's wanted by both going for the long term.
I've asked, and been asked by my spouse at various times something the other was curious about, and accepted when informed, or told the other, "That's private". You haven't yet realized it's ok to do that, and just because you're asked, doesn't mean you're going to get, or have to give an answer. This isn't just about sex either. We don't have secrets from each other, we have respect to let the other person have their own past, and enjoy the memories of something meaningful to us personally.
At 21 I was the same as you. You think I was always so ready to let sleeping dogs lie sometimes? I speaking from painful experience. I fact, I realize now there wasn't much chance at being heard, I mean really heard by you, at this time. I sure wouldn't have listened to someone like me at your age.
Good luck with your relationship with a guy that was already jealous, this sure isn't going to help it.
It'll be a learning experience for you, and will hopefully do you some good done the line.
