The Captain America: The First Avenger star said that his life was "great" before taking on such a high profile role, and admitted that he struggles to cope with the amount of attention that comes with fame.
"The commitment was huge and there was sure to be a lifestyle change that I wasn't sure I was after," Evans explained to Parade. "Not being able to go to the gym, go to the grocery store, walk down the street and not have people recognize me.
"My life was great. Well, not like it's bad now. It's been saturated in anonymity…What do you do on a Sunday? What if wherever you went somebody is gonna walk up to you and want something from you. Which is okay sometimes."
Evans added that he made the decision to take part in Captain America willingly despite the drawbacks.
"I knew what I was getting into when I got in the business. I made my bed and I was going to sleep in it. It's great if it's a 12-year old, but sometimes it's a 40-year old dude. Sometimes you just want to be left or want privacy," he said.
"What if something was going bad in my life, like my mom was in the hospital, or what if something good, like I was getting married or had a kid? Some moments you just want to have for yourself."
Evans recently insisted that he does not consider himself to be a sex symbol and revealed that he is "drowning" in insecurities about his appearance.
Captain America recently became the highest-grossing superhero debut of the year, taking an estimated $65.8m (£40.4m) on its opening weekend in the US.
