Why do nightclubs turn me off ever since I got married?

You have outgrown them. You are maturing. Let that scene pass out of your life and find something enjoyable to do with your wife.

Why do nightclubs turn me off ever since I got married?

Now that I am a married man and was engaged to the woman I love , I don't see the reason of going to a place that people use as a singles bar/club.

You answered your own question.

Ok, so then avoid them and don't worry about it. You've had plenty of experience and now you are at a different stage in your life. Sounds like you've grown up

You wanna know why? Because you know there are gorgeous looking young girls with hot bodies in there but you finally realized that you're not who they're looking for. Makes you sick, doesn't it? Yeah, keep telling everyone about that great gal you got.

You answered your own question. You thought of clubs solely as a place to meet people to date or hook-up with. When you no longer felt the desire to do that, clubs lost their appeal for you.

Plenty of people just enjoy going clubbing for the experience, the music, dancing,drinking, socializing, etc and don't use them to hook up for sex or find people to date. Lots of couples go to clubs together. To each their own. I bet your wife is glad you've lost your desire to go clubbing.

keep in mind your brain continues to mature. what seems like good fun when you're 20 won't be the same when you're 40

"If I met someone I had the right to pursue them. I had no shame with whatever happened. "

Um ... that's not something to be proud of.

Your feelings are healthy and normal.
